8800GT SLI crysis lag?

Hey all,

I'm running the spec's posted below and I'm still receiving lag in Crysis running 1024 x 768 resolution, Very High Settings (Running XP using the Very High Settings Tweak), and 16Q AA. I'm only getting about 15 - 20 fps most the time, hardly playable! I tweaked the memory timings and such a little bit using nTune, overclocked the gpu to 690 from a stock 640, but I'm still lagging! Given my specs below what would you say is the cause of this? I would think that 2 8800GT's in SLI would run Crysis at full settings fine?

Specs
---------------------------

Motherboard: ASUS M2N-SLI Deluxe AM2 NVIDIA nForce 570 SLI MCP ATX AMD
GFX: 2 x 8800GT XFX Alpha Dog Edition
PSU: Prudent Way 650W SLI-Certified
MEM: 2 x 1gig Patriot 800 (Running stock @ 2500 bus, I overclocked to 2700)
CPU: AMD X2 4600+ (2.4ghz)


Any suggestions are much appreciated!

Thanks,

- Jon

Turn off AA or lower AA?

Lowering AA will definitly help, and putting a bigger resolution could help too. Because smaller resolution put more stress on the cpu and he might be a bottleneck.

Yeah, you want more resolution. When you have more resolution, it allows the graphics to work harder. Right now, the CPU bottlenecks it at 1024x768.

Simply put man you could be running 8800 ultras in SLI and if you got
settings on very high with AA turned up all the way you will still have problems.

I mean didnt you see the benchmark with 3 way sli, 40 to 50fps, i mean iknow the resolution is a lot lower than 24,26,38, and 30 resolutions.

But those cards will also kick the crap out of an 8800GT, and the game
is like always barely playable with everything turne up.

Check out the review on the new GTX 260, and GTX 280 cards and you
will see its not just you, Crysis really is that graphically demanding, or
the code is really bloated, take it how you want, but its the truth.

8800 GT for all intents and purposes is a fantastic card, at an unbelievable price. Comes very close to what the orginal 8800GTX card could do.
But Crysis was really built for tomorrows tech, and by tomorrow, Crytek means whatever generation of cards comes after these gtx 260, gtx 280, and HD 4850, HD 4870 cards :)

16Q AA.

I'd be surprised if you could run that in a DX8 game. 16xQ is stupidly high. Going from 16x to 16xQ took me from ~30-35FPS in oblivion to 8FPS. It's a stupid setting that should be removed. Try running at something normal, like 4x. At the very most, go 8x.

yea think you will find when you have a look around that nothing runs crysis on full at high res yet and just have to put up with it. however if anything was bottlenecking your system I would think it was definitely your cpu, unless I am have got the wrong cpu you would really need to upgrade that to a much better version like a phenom, advantage is that they are very cheap compared to intel ones.

1680 x 1050 is the sweet spot for your cards, below that and SLI is not really being used.

Also, I would try OCing your CPU a bit, at 2.4Ghz its probably holding your GT's back a bit. If you can get her up to 2.8-2.9 Ghz it will help.

But the fundamental problems are your level of AA and your resolution.

For sure the X2 4600+ is holding back SLI 8800GT. Asking that CPU at stock clocks to run Crysis with all High settings including physics, is asking way too much from it. Set physics to medium and see how much it helps.

Also, agree set fsaa back to 4x until you get things running smooth.


edit: ? for ya, ... are the 512MB or 256MB versions? The 256MB suffers huge in crysis and 16xaa would make the thing cry for mercy.

Thar's your problem.

Stick to 4xAA or even 8xAA. 16xQAA is ridiculous.... How can you tell the difference past 4xAA lol? Amp up the res to 1280x960 (or whatever your monitor's native is), and take the AA back to 4xAA or even 2xAA. Ever wonder why the Crysis benchmarks rarely add AA?
