Assassin's Creed: Brotherhood performance issues with m18x.

This game doesn't support crossfire apparently.

When I first began playing it, I was getting 12-20 frames in the opening level. I then disabled crossfire, and it went up to 50-60. 40 frames with totally maxed settings (multisampling, etc). Still some drops here and there, but mostly capped framerate. Then I learned to force a crossfire profile with RadeonPro, specifically the Assassin's Creed 2 profile. I renamed the .exe AssassinsCreedIIgame.exe, and now crossfire was working and I was getting 60-100 frames with completely maxed settings. Great.

I beat the first level, get to Rome, and the framerate is back to 12-20 for some reason I can't understand. I thought maybe this level is just way more graphically intensive (which still doesn't make sense because my machine should max this entire game easily), so I went back to previous levels and the framerate is back to being crap.

I have no idea what to do. This is really a pain. I can't even wrap my head around why the performance dropped back down. This was all one gaming session. I made no changes to the profile or anything.

Has anyone figured out how to fix this damn game?

 

This is such bull.

Just once I'd like to get a game and not have to spend five hours just trying to get it to work right with crossfire/ATI. I've yet to buy a single game that has worked fine right out of the gate.

 

Same here man (I haven't tried Brotherhood yet, but will eventually). Almost every game that I've played, I'm having issues. Many of them don't make any sense at all, I just have no idea what to do. Everyone else seems to be having much better experiences with their machines and getting great FPS with games, while I'm stuck trying to figure out why my performance is lacking.

 

And I literally just bought this game 5 minutes ago of me posting this reply.

Sigh.

Really though, the only game I've been having trouble with is Total War: Shogun 2 but it's fairly glitchy and buggy. I recently wiped my machine (again) and the game seems to run a lot better now though.

 

What's so vexing is that I had everything working right for hours. Then I load into a new level and everything goes to hell. Now I can't get even half the framerate I was getting before and nothing has changed.

Before, with crossfire off, it was 40-60 frames. Crossfire on, 60-100

Now, with crossfire off OR on, 15-30 frames. I've tried without RadeonPro, I've tried with (with Assassin's Creed 2's profile forced), and nothing is working.

I'm going to go to the gym and come back and do a fresh reinstall of the game and see where I can go from there. Very frustrating.

 

I've noticed in a couple of games now there are glitches when first starting it up/resuming old settings. Crysis 2 comes to mind, whereby I have to take Ultra -> Extreme, Click Apply, Extreme -> Ultra, Click Apply before the framerate goes to normal for ultra. This happens every time I start the game (after first install).

Try something like that, haven't figured out the cause yet but that has always worked for me if the game settings glitch out or the framerate is too low.

 

I've fiddled with the graphics settings in-game like that about five hundred times. No good. With everything set to lowest, 15-30 frames. With everything set to highest, 15-30 frames. It makes no freaking sense.

 

Definitely sounds like the same problem I've been having. Not even changing the resolution back and forth has any effect? Almost sounds like it's locked in a low power mode for some reason. GPU-Z is reporting the 715/900 on both cards and not any other low mode like 100/150 (or whatever the number actually is).

 

GPU-Z is reporting perfectly normal values.

Changing the resolution barely has any effect whatsoever. I took down the resolution WAYYYYY low, to the point where half my screen wasn't even being used, and I gained like 5-10 frames max.

 

Something is definitely wrong if you can't even get over 30FPS at 800x600 or whatever the lowest is. The card should scream up to at least 60+ at the lowest resolution even with all settings maxxed. What driver's are you running? I had issues with the dell drivers so I don't use them at all.

For reference I'm running 11.8 Preview July 12 with CAP 11.7 (whatever the latest is on AMD website).

Here's the link in case your wondering.
AMD Catalyst? Control Center / AMD Vision? Engine Control Center 11.8 Driver Preview for Windows 7 64-Bit Edition

If it's not a driver problem I would definitely say one of the cards is toast.

 

assasins creed brotherhood was faulty from day one what surprise me is that they haven't fixed it yet

when i played it it was varying between 20 to 40 fps in a verry unstable way

 

I have 11.8 preview with 11.7 CAP

 

Reinstall fixed it.

Hope it doesn't randomly mess up again.

Only problem now though is that the game has no sound. Sigh. Nothing's easy.

 

OKAY fixed the sound problem. I had to set the launcher setting in RadeonPro to "Windows Live." Not sure how that's related, but it was suggested by someone else and it worked.

Christ. NOW can I play my damn game?!?!?

 

I find it strange you were getting FPS issues. I was maxing that game out very well on my 5870M Crossfire setup w/ i7 720QM with about 50+ FPS. Strange.

 

Only on ATI cards. On Nvidia, it works flawlessly.

Yesterday I installed 11.8 and brotherhood on laptop and although fraps gave me 70+ frames, it wasn't smooth as my desktop using an old 8800gt sli... Very strange! More than 60 frames but the game was like gasping.

 

My performance seems silky smooth on AC:Brotherhood after installing 11.8 on my PC yesterday. I don't have Fraps numbers but I do have everything maxed out and it looks and runs with no hitching. It's amazing what a good driver can do.
