Crysis SLI Performance Feedback - Page 18

Revs · 07-28-08, 05:30 AM

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

Running one GT

Running GT's in SLI (more than double FPS!)

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!?

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...

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.

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.

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...

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.

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

Where did you get that wallpaper?

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.

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