Just got my 880M twins!

Hey @Kade Storm , well actually I made a mistake in the settings menu, forgot to relaunch the game so the settings did not take effect. My 51fps was with debris and smoke effect off. I have physX set on my second 880m and I now can constant 34fps on average. What about you? I doubt my 880ms are at full load though. I reckon it's between 70%-90% drops a lot. @Ethrem, can you tell me what your 980ms get? I did read that WB are working to fix a rendering bug for gaming laptops. I guess our performance will be drastically higher once they port it correctly.

 

Yeah, they removed buying option for the game's profile and are working on a series of patches to address these issues. No surprise. At this point, I'll take the 30 FPS if they at least get the rain shader, ambient occlusion and textures running. Apparently, the first patch managed to provide these features, but I can't seem to find them, not even with a new game save.

As to your performance. Yes, you're right. Under SLi, the performance on the second card is low. Disabling SLi, and dedicating the second card to PhysX improves this in some important respects. While my average FPS didn't increase much (approached 38-40 fps), the lowest frame rate was much higher, so it is much more stable. Although again, the game is still failing to take full advantage of the cards. I regularly see the second card being underutilised at 50% while even the primary card has its 70% moments.

Further patches are supposed to address the SLi issue.

 

Thanks a lot Kade Storm. I just can't fathom the idea of my most awaited game of the year running like a piece of trash where even a quad Si Titan x is put to shame. I guess I'll just have to wait now. Hey, I was wondering, do you have a custom VBIOS for your 880ms? Also what fps do you get on crysis 3 maxed out with anti aliasing set to txaa med and motion blur medium, assassin's creed unity maxed out with masa 4x? I personally get on average 58fps for crysis with the aforementioned settings and 45 (varies a lot) for ac unity. Thanks a lot

 

The only way to get decent performance out of this game is to use Inspector to delete the AK profile and attach the game exe to the Unreal Engine 3 profile. This basically kills the second card but performance goes up 20-30% depending on the scene. I posted my results in the AK thread.

 

Nice can you link me to it. P.S. I just got lost in the technical jargon :/

Better?

 

Thanks

 

Thank the Fox bro... Game stuttered like crazy til his tip... But I can't play past the Batmobile since I haven't played Batman since



Like for real... I never beat that boss... But I was also like... 12.

But I got all the games as far as I know... There were 4 PC right?

 

heheheheheheh a Batman fan huh Well I am a Batman fan too which is why the arkham knight was my most anticipated game of the year. Yup, that's right, 4 batman games on PC, Arkham Asylum, Arkham city, Origins and the latest being the Arkham knight. I bought them all a couple of weeks back, had a crazy sale going on for them (-75% for all titles except Arkham Knight).

 

Hey @Mr. Fox , I just ran Batman arkham knight with SLi disabled. So, it's only one 880m rendering stuff and dealing with physX at the same time. I got 28fps on average. Can you tell me what fps you get with SLi disabled too so I can compare?

 

With 780M about 36 FPS average and 980M about 45 with SLI disabled.

 

Nice,were the GPUs overclocked? Can you tell me what settings or file you tweaked to get that performance? I am still running tha game without any tweaks and gameworks on which is why I think the performance is horrible.

 

Checkout the gaming thread on this game. Brother Fox did a massive post with all his tweaks there.
My suggestion is wait to the game is properly fixed. It's a broken POS.

 

Yeah, at this point, I am just waiting for a major update. Right now, it's just a piss poor port filled with glitches and hideous looking textures. Hey does anyone have an oculus rift? I am thinking of buying one but I don't really know what the PC requirements are.

 

Posted some new info today. http://forum.notebookreview.com/thr...tem-requirements.775079/page-21#post-10035460

 

For the vanilla version of Arkham Knight, the facts are clear: no proper SLi support from the people who made this game at the moment. We can only give credit to the work being done by end users, such as Mr. Fox, for finding out ways around the issue. Anyway, if you have SLi disabled, then dedicate the second card to PhysX and you'll get performance similar to what Mr. Fox is getting with his 780M configuration. I am getting around 38-40 FPS with that setup depending on how much the test glitches. Also, to be honest, in-game performance is quite a bit better than the benchmark. My concern is more about the instability, even with this initial patch. When one starts the game with a new save, the rain shaders look absolutely stunning, but upon resuming the game, the shader effect becomes vastly reduced. The only way to avoid this issue is to either play the game the whole way without ever closing the application, which is absurd, or constantly restarting with a new save, which is also absurd. I'm very disappointed by this because with this patch, we see an excellent example of how good this title can look, but due to utterly poor initial Q&A procedures, if any, we can't maintain that quality and are still falling well behind what the consoles produce visually out of the box. Nevertheless, at least Rocksteady is working on the issue and the patch notes are clear that further work will be done to improve those shaders as well as introduction of SLi support. Until then, though, I won't be progressing further in this game because I'm damn stubborn about quality visuals and immersion, even more than I am about compromised 60FPS performance.


Re: Custom vBIOS

While I do regularly use the custom vBIOS for testing purposes, generally speaking, I do not, and at the moment I am using standard vBIOS. This might come across as tad controversial but I find that with most of the newer titles, the cards maintain decent clock and I have little need for consistent extra boost. Either a game is generally running around the 60+ FPS mark, in which case the extra 39 MHz hardly makes an appreciable difference, or it is a game that is lagging far behind for other reasons where again, that added 39 MHz is of little consequential value to my ventures. Now where I do find the custom vBIOS helpful is in those particular titles that show a tendency to fall prey to random and substantial sthrottling as well as older benchmarks, but at the moment, I've barely got time to try out some games, so the stock vBIOS is doing a tolerable job. At the end of the day, it's about one's own requirements in such situations.

I'll address your queries about game performance in reverse order because I like to save the better game for last.

My performance in Assassin's Creed Unity, with everything maximised, as you asked, is around 45 FPS. I tend to favour maximum TXAA over MSAA, which is about the same, perhaps an extra FPS or two. Also, with the game itself, since I'm not focussed on getting the best anti-aliasing performance, I am quite content with FXAA, in which case I get over 60 FPS on average. Of course, the cutscenes in this game, which a lot of people can speak for, are a disaster in terms of performance; much slower than the actual game itself.

A good while back, I had run Crysis 3 at absolute maximum settings like BigKrazy in YouTube, even with 8xMSAA. I got similar performance to his output. On the settings you asked for -- medium TXAA and medium motion blur -- I get around 45-80 FPS depending on what is taking place on the scene. I'd put the average itself at around 60 FPS. Again, I'm just as content using minimal TXAA or even FXAA, which substantially boosts the performance.

With the custom vBIOS, the above-mentioned games perform about 10-20% faster, but that does come down to driver quality as I have found that with the newer drivers Crysis 3 doesn't throttle the clocks down as much, just as it didn't with the older 326 series of drivers.

As can be expected, our systems exhibit similar performance.

 

Thanks a lot @Kade Storm , a very lengthy post indeed but extremely detailed I am running the stock VBIOS too, never ran a custom VBIOS as I am afraid of bricking my cards should I fail the installation. May I ask what temperatures you observe when running the custom VBIOS (I heard it's generally a lot higher compared to the stock one)? Actually I am a subscriber of Big Krazy (a very nice guy). As is to be expected, you and I get the same fps. AC Unity with everything maxed out and MSAA 4x, I get 45fps on average. Crysis 3 everything maxed out and MSAA 8X in @welcome to the jungle@, I get 40fps on average. Very similar performance indeed. I was wondering, how long do you reckon the 880ms to be able to run games at ultra? I was thinking till the end of 2016 to the start of 2017 seems feasible enough. From what I gathered, the difference between the 880ms and the 980ms is roughly around 15-20fps which further supports my estimate lifespan suggestion. Which custom VBIOS would you recommend me as sooner or later, I'll need that extra amount of power given that I am trying to squeeze as much as I can from my 880ms and eventually upgrade to the 1000m series once they come out.

 

Heh. No worries. Although you do ask questions that beckon a decent response length. At the risk of another lengthy post, however, perhaps we can take this enquiry into a private message. ; )

Edit:

And yes, cards run mildly warmer since they constantly retain a 993 core clock, but that is to expected and the heat doesn't overwhelm the cards.

 

hihihihihhi Okay. Also, I forgot to mention this but my 880ms run at a constant 993MHz in games with stock VBIOS.

 

can you post your bios? mine runs like dogpoop :C

 

Sure !

 

Careful.. you have 4gb 880m. Flash a 8gb vbios on it and you'll have a paperweight.

 

Ain't that dumb, I just want to compare it with mine. I tried to make my own bios but it didn't work, even bricked the then unbricked it. I'm not sure what to change in the power table, first one is tdp, i tried to bumb it with 15% but it didn't work, looks like i have to tweak something else. Can some one help me? the card isn't even reaching 70c while gaming.

POWER TABLE by CakeMaster posted Jul 30, 2015 at 6:15 PM

 

Wow those are some nasty figures man, not even reaching 70 degrees? WTF, are they just running at 405MHz? I would really like to help you but as Tbonesan said, I have the 8gb version. It'll probably just brick your system. Why don't you upgrade to the 980m? It's a much safer thing to do rather than trying to fix your 880m. It seems pretty dead to me.

 

I ripped out the fan and slapped in a desktop one which I control from a circuit connected to the wall, and I got some other fancy stuff aswell against heat, I sold all my pcs and laptops to get this ****er cuz I'm moving often and needed a laptkp that fits in my backpack. Talking about the bios, you said yours is not throttling, so I wanted to take a look at it not flash it, just to see what is different from mine, then I try your bios settings set up into mine and if bricks I can still flash it back to stock. I really lost count how many times i bricked it lol

 

It will brick your system, no question, if you flash a modded 8GB vbios to your system.

The only thing you can do... Is change the 117000 power limit to 150000 and hope it makes a difference. If it does not, unfortunately, there is nothing else that can be done without a vbios hex edit. You would probably have to donate a lot to get someone to take the time. The cards are broken. And were quickly abandoned by devs. Because once they pull away the limits they shoot from 70s to 90s.

 

Sure, I'll upload my VBIOS in a few hours time(kinda busy at the moment) but if I were you, I would probably just sell my 880m and buy the 980m cause as @Ethrem said, they are broken beyond repair. My 880ms are probably performing exceptionally good due to Dell tweaking the VBIOS before shipping it to me if I were to take a guess. Anyways, I am pretty sure that Dell has something to do for my 880ms performance. I guess you can kinda say that I am lucky.

 

Can't get a new gpu cuz here in europe we pay waay more for such parts and this was all the money I had.
I sold 2 pcs and a y580 for 1k, and I got this for 900 euros lol. So, I dont think that someone gonna buy this crap anyway plus the 100 left wouldn't cut it.

 

Is that the only column that i have to change? What about the first one, isn't that the tdp?

 

Well even though it throttles a lot, it still manages to run games decently right? It just won't produce the performance it was technically designed to so I am pretty sure you would be able to sell it rather quickly at a bargain price for ex 250-300 USD. Or just sell your laptop if need be. An ASUS with a 980m should be fairly cheap so maybe you could consider switching to ASUS.

 

The cheapedt laptop with a gtx 980m here costs 1600 new or 1400 used, later I try to compare your bios with mine mess with the power table the last time and shoot myself.

 

Unfortunately... no. It makes minimal difference. You need a hex edited vbios.

 

Just curious, does anyone remember what driver the 880's launched with? Did they perform any better with the first driver or one of the few after launch than they do now?

edit: Nevermind, they weren't on the geforce driver page but found them on NVIDIA.com
