Crysis SLI Performance Feedback

[Mr Bigman]

Yea, but its wurrysom

[Soetdjuret]

I can tell SLI is helping me play at 2560x1600

Aww mann it looks crisp on that rez! :captnkill:

25 fps on veryhigh using that rez tho :/ but it doesn't feel that laggy, only a bit kinda slow-ish...

CRT monitors FTW, allways better graphics when u raise the res...1280x1024 witch is the native rez on my crt isn't comparable to 2560x1600.

What setting do you use for SLI in Crysis?

It says single GPu recommeded in profile which ain't right so what is a good setting?

I noticed this too, but when i changed to forceware 174.74 i could choose "nvidia recommended" it was on as default aswell.

I'm beginning to tire of SLi...

My first experience with SLi was like Heaven... it was with dual 7600GTs. There were situations where I saw over 2x the performance of a single 7600GT. Then when I got my 8800s SLi just never seemed to work right.

Sold that rig then got the one I have now. Tried two 7900GTs and once again... just never could get it working right. Pulled the two 7900GTs out and put in a single 7900GT 512MB... happy as can be. Gonna' put in a 7900GTX just for kicks to see how much better the GTX can play Crysis than the GT.

I was gonna' go for dual 8800GTXs... but I'm gonna' hold off to see how well the new architecture they're gonna' release performs. Right now this 7900GT (soon to be GTX) plays everything just fine, save for Crysis.

Latest nV-GeForce Driver – 175.16 for Vista_x64


Display Settings: 1920x1200/DX10-64bit-HDR/AA-4x/Object Quality-VHigh/ALL Rest-High.


Results: Min=25-FPS/Max=40-FPS/Average=33-FPS


Note:
With AA-OFF, all result rates increase by 5 FPS.

Comments:
Any PC game that depends on speed and interaction with I/O resources, such as video frame rate and command keys, has to cruise around 60 FPS. So playing Crysis below 40 FPS, I am not in full control of the game – hate to die for no reason :) For now, Crysis is awesome eye candy with realistic motion graphics, 3D/HDR visuals and earful of quality digital sounds.

Hey aloofski, remove the AA and you can use "Veryhigh on the cheap" tweak for better graphics. It will sure look better than what it does now. Here you go, try it out.


'Very High' On The Cheap

There's another thing you can try if you find Very High mode is just a bit too strenuous for your system. You can try the "cheap" version of Very High, which basically only implements the more obvious visual enhancements of Very High. To do this, instead of editing your .cfg files as covered above, all you need to do is set your in-game settings all to High as normal, then add the following commands to your System.cfg file (or just test them in the console first): r_UsePOM=1, r_sunshafts=1, e_water_ocean_fft=1, q_Renderer=3 and r_colorgrading=1. This will make High look extremely similar to Very High in most respects, but with quite a bit less of a performance hit. In a pinch, if you still need extra FPS, try disabling one of the effects, though keep in mind that q_Renderer=3 is necessary for color grading to work. You can also turn off Edge AA (r_UseEdgeAA=0) to make things look crisper and boost performance further.

Crysis has terrible SLI scaling. It only scales under some resolutions, under certain settings and it makes things worse, most of the time.

Example:

Windows XP32 - 1680x1050 - DX9 - All High - GTX280
Single Card: AVG - 51.7 Minimum - 32
SLI Enabled - AVG -45 Minimum - 25

I have also replicated these results in-game with consistently lower FPS when SLI is enabled...

What is this? In the worst possible scenario, IT SHOULD NOT IMPROVE AT ALL. Not make things worse... This is unbelievable...

CoD4 and DMC4, now these games have great scaling...

[Revs]

I get 100% scaling in Crysis. Or at least I did with my GT's. Not tested the GTX's.

Just noticed you've got two different cards. It shouldn't make a difference, but it's something to look in to. I would try flashing them with the same BIOS. I assume you've tried different drivers!?

[Lfctony]

Can you test using the timedemo at a non-GPU limited situation? 1680x1050, DX9, High with single and dual cards? It might be that my CPU can't handle the extra overload of syncing the cards...

I have tried different drivers. The thing is, it actually scales when I force AA or try Very High. The thing that I find weird is the performance drop when it doesn't. Also, this happens in Crysis only. In other games, it scales great...

[Revs]

I ran the GPU test a few weeks ago and it all seemed to be scaling and running fine. I'll do another test tonight with and without SLI enabled. I'm at work ATM.

Just something to test... Try swapping the cards round in the slots.

[Lfctony]

Mate, I don't see the reason. I mean the cards scale in other games and in Very High Crysis, so I don't think they have any problems or anything. My only question is the overhead SLI introduces. If you can at least reproduce my results at the specific resolution, then it's pretty obvious we're talking about crappy scaling with the SLI overhead making it worse.

[Lfctony]

Been doing some testing. Apparently I am very CPU limited! Go figure, at 3Ghz with a Quad Core... I dropped Shadows from High to Low and I got somewhat better scaling. Regarding SLI, it was enabled at a map where I was receiveing minimums that where determined by my CPU. Enabling SLI overloaded my CPU to frames below 20 making the game unplayable... :( Looks like I will have to settle for medium shadows for SLI...

[Quick420]

You're only running an FX-60 though. You might be experiencing a CPU bottleneck. I'm wondering what somebody with a Core2 at 3.4GHz+ would get if using SLi... hopefully better results.

It runs ok now but still low min fps,maybe 2gb's more ram would help?????

I would say so. With 2Gb of ram I noticed stutters in open areas when looking around, due to the textures loading. When I went to 4Gb the stutters pretty much went away, because the game could keep more textures loaded, therefore there was no waiting for the HD's to load em up. Also, the more physical ram you have, the less the PC needs to use the (slow ass) page file memory.

So, yes. More ram should help loads with your minimum FPS :).

EDIT: It's even more of an issue in Vista because the OS chews up more of your ram.

[jcrox]

Moving from 2 to 4 gigs of memory made a major difference for me as well with Crysis

Where did you get that wallpaper?

[AngelGraves13]

My new rig plays Crysis Warhead beautifully.

Crysis runs great as well, though I get some sound pops from time to time.

I think my video card needs more RAM. I'll upgrade when a DirectX 11 card is out.

Woops...didn't see SLI in the title. I'm referring to a single card.

[lapino]

And not texture popping, bad or no AF etc? Seems somethings wrong with Ati?

Thats a nice background you got, where did you get it, can you share it?

Know what? U should put a new folder on the desktop called "games" or "game shortcuts" and put all your damn shortcut icons in the taskbar in there...

[Sean_W]

I've just not long brought a 9600GT and have a nForce 680i mobo with SLI. I'm really thinking of buying another card based on this. http://www.firingsquad.com/hardware/geforce_9600_gt_sli_performance/

So it would only cost me £124 for SLI which beats a 8800 Ultra and is much cheaper. :captnkill:

How would or does Crysis/Crysis Wars scale with two GTX-285's at 1680x1050? Am I correct in saying Crysis will NOT benefit from a PhysX card?

[Revs]

I got about a 90% increase in performance with my second GTX260. In fact it scaled very well in almost all games. Crysis doesn't use PhysX so no, a PhysX card would be useless for Crysis.

EDIT: GTX285 single vs SLI in Crysis...

Single: avg: 20FPS
SLI: avg. 38FPS

Yup, scales very well!

Nice! Thanks.

What scares me about that link is the results in Company Of Heroes. Much worse with SLI. I play that game a lot too. With an SLI setup can you turn it off for games that suffer under it? Is it easy to do?
