Batman: AA performance on ATI card?

I'm using an ATI 5650. I've played AA before and the performance wasn't very good if I put any of the settings up.

I'm wondering if there's any way to speed the game up? I've heard that physx is a problem.

 

2 thing:

AA=he destroy the performance in ALL games(with medium and some high class gpus),the 5650 is a fantastic medium class card but the max AA you can make without drop in performance is 2x

phisix=if you have the option on,sympli turn this off

 

Alright. Last time I played I remember having to turn the resolution down to 720p, which was a shame. We'll see how it goes this time.

I may also have been on ATI 10.2 drivers.

 

Physx is an nvidia only thing btw. Even if you had some option in game to enable it while on an amd card it would do nothing. Still it shouldn't hurt to disable it if there is an ingame setting.

Also with mid range laptop cards I would not even bother with using AA. Too big of a performance hit and not to mention you are playing on a small screen and should not notice the jaggies on the edge of textures much at all.

 

If I enabled it I assume it would be handled by my CPU.

Also, when I said "AA" I meant arkham asylum, not antialaising, in case that's not clear.

Definitely going to try to keep AA down to 0 or 2 depending on how well it's performing.

edit: Anyone with my GPU play the game? I overclock to 700/900.

 

Ah my bad about the mixup. But ya physx is a nvidia only thing and runs off a nvidia graphics card, proprietary for nvidia. If it was an open physics option like Bullet etc., it could be offloaded to the cpu.

 

I see. Well it's a shame that games do things like that.

Is there any way to get physx on an ati card?

 

Only in a desktop pc environment. In that case, you would have to run a secondary nvidia card with hacked drivers along side your main ati/amd card.

 

ahhh but you have bad performance without AA on this game??with a 5650??i have the same vga,and ths baby can handle games much more heavy than batman...update your driver to 11.4 preview that are the best driver i ever used on this baby ati...if you not solve is strange...normally the 5650 can handle this @1366x768 maxed out...

 

AA = Arkham Asylum, not Anti-Aliasing. He never said he has problems with Anti-Aliasing.

PhysX is always on. The option in game just turns on PhysX hardware support. If it's off, just means PhysX is running on CPU. You can't turn it off...

You can try reducing graphic settings and resolutions. That's all you an do. Turn off bloom, HDR if that is option etc.

 

Well, its clear no everybody who answered has played the game. Since you have an ATI card PhysX should be off (not sure if you can make PhysX go into the CPU, but it will for sure slow down the game).

Maybe updating the drivers can give you a boost.

 

guys TURN OFF PHISIX...in ALL games that have this option and if you not have a nvidia,you have HUGE slowdowns!!sympli you not are able to process phisix effect decently on cpu(you can have sure a i7 sandybridge ultrapowa but not go good for phisix)...and next phisix is the best stupid features that can have a game

this is a video of batman benchmark on 5650 with a i3:
YouTube - BATMAN ARKHAM ASYLUM BENCHMARK 1366X768 ACER ASPIRE 5740G CORE i3-330M ATI 5650 Mobility @675Mhz

i think that a averege of 60fps is not bad...

 

I am downloading the demo at the moment, and I have a 5730, a little better than yours. I will report back after I play.

 

You should've no problems for all high in 768p.

 

Just played it :

EVERYTHING MAXED, including PhysX to High : 10+ FPS ( PhysX bottleneck? ), but mostly, goes to 25+

EVERYTHING MAXED, no PhysX : 25+ FPS never dropping below 20. Mostly 30 FPS.


ON 1080p

 

I own this game, but haven't still installed it on my M15x... I will give it a try one of these days.. i remember is was fun, most of the time... except for those damn exploding gargoyles...

 

Yes, PhysX is the bottleneck as gieffe22 has stated multiple times. PhysX takes a lot of CPU time to run on an ATI card because it's an Nvidia branded technology and can only be accelerated with Nvidia cards, and that means it's taking CPU time away from game-centric things like AI, collision detection, etc. Physics calculations aren't cheap even on an Nvidia video card, and they're even more dear on a CPU.

I'm not even sure if it runs in a separate thread, or that a CPU with more cores would help.

As an aside, anyone with a 5xxx series ATI card should really be using an 11.2 or later Catalyst. Ideally 11.4. It's a major performance boost over the older drivers.

 

Yep. I will play again with PhysX and compare normal vs high, and will monitor the CPU usage.

Also, I'm using 11.4 preview drivers from march 9th.

Also, kind of off-topic, but why is my display kinda blurry? I mean, some buttons in the OS and in firefox are kinda blurry, what is the cause of that?

 

you may have morphological AA turned on somehow (that "software filter" AA thing)

...but that's more for in game when turned on..not sure if it even does things out of games.

 

When no nvidia gpu is detected and physx is enabled it defaults to a single threaded mode which severely caps performance. Cpu's are more than capable of physx acceleration performance wise but nvidia intentionally caps the performance off so u have to get an nvidia gpu to reap the benefits. It is possible to lighten the load on arkham asylum by editing the ini file (just google "batman ati physx" for tutorials) which gives you around 30fps with a high end i7 but this lowers physx simulation quality resulting in small glitches and things flying where they shouldn't.

Physx is an nvidia technology and they want it to stay that way, and with today's processors being as powerful as they are, the only way they can insure it stays that way is to cap performance by single threading everything.

 

Wow, really? Thanks for the info +rep

Nope, MLAA is disabled in my registry. I didn't touched it, only other nice features that are related to textures, etc. Can it be a bricked GPU?

 

I get higher CPU usage with PhysX on high, but I have a HUGE FPS loss, but the CPU is NOT on a single thread or at 100% usage. Here are some screens :

With PhysX on High :



Without PhysX :

 

Doesn't necessarily prove anything. Nvidia could be doing something with PhysX that basically requires the CPU to query the GPUs memory which will slam the PCIe bus that is already mostly saturated, which is what will slow EVERYTHING down and still not peg the CPU. They're probably doing calcluations off of GPU geometry instead of an internal model. Which would also explain why the GPU PhysX processing is so much faster, because it's just a shader program that uses internal GPU memory, and GPU memory is orders of magnitude slower copying back to system memory than it is just running entirely within the card. It's not intentionally crippling the software, it's just making a design decision that is basically forces using the GPU instead of the CPU. Same reason that tesselation is done entirely within a graphics card instead of done on the CPU and the increased geometry pushed over the PCIe bus.

 

I'm running AA with max settings (no physx) and it's working great. Just thought I'd let you guys know. Physix drops FPS to half.
