Who got SLI to work?

[Who got SLI to work?]

I used the EVGA SLI Enhancement and it has made quite a difference. My framerate essentially doubled in all scenarios, from the menu to the game play. I highly recommend it to anyone having issues with SLI:

Here are my specs:

Intel Core i7 920 (3.8 GHz)

6 GB OCZ Platinum DDR3 (1600 MHz)

2x GTX 285 - SLI

2x 1.5 TB HDD - RAID 0

Windows Vista x64

1920x1200

In-game settings:

Visibility: 3600

Quality preference: Very high

Interface resolution: 1920x1200x32

3D resolution: 1920x1200

Texture detail: Very high

Video memory: Very high

Anisotropic filtering: Very high

Antialiasing: Very high

Terrain detail: Very high

Objects detail: Very high

Shadow detail: Very high

Postprocess effects: Very high

Interface size: Very small

Aspect ratio: Very high

I now get 55-65 fps in game so far (note: I only have the demo right now).

Change the exe name to crysis64.exe. But realistically, you can't max everything in A2 and get a constant 50 FPS (for now anyway) at that resolution, you're going to have to compromise.

I've done that also, and I've forced different SLI modes. To say I can't "realistically" expect to max it, that's preposterous. I get a constant 60 fps on Crysis maxed at this resolution with 4xAA and 16xAF. To get half that on this game is a joke. The point is that SLI is not utilized in this game at all, or at least not in the demo. If I disable SLI, my framerate is the exact same, so that's proof enough that SLI is not used at all. If I force SLI using split-frame rendering and/or alternate frame rendering 1 or 2, I actually get worse performance.

I don't have to compromise. I don't have to buy either.

I'll keep my eye on this before I go spending any cash.

Edit: I renamed it to Crysis.exe, not Crysis64.exe, as I saw in another thread. I just tried Crysis64.exe and I'm now locked at 60 fps, so thanks for that. Still a shame I have to rename it at all in order for it to act right. I'm going to keep tinkering.

Solved a few issues here:

182.50 nvidia driver = GOOD - newer drivers = graphical grossness/flickering.

Leave default nvidia setting in the control panel BUT disable Vsync and the gtx flies :)

I tried with performance setting on the texture filtering and that helped also.

Using the -maxmem=2047 -winxp

i7 @ 4.00 D0 with Gtx295 on vista 64 - 6gig.

Get 140fps on intro screen - 30-44 in multiplayer

running at 1920*1040 (native) and 100% fillrate.

Hope that helps - the driver change reallY helped me get a better result.

Also remove your cfg file after making these changes and sort out the settings in game.

Turn fraps OFF = W O W :)

What in-game settings are you using?

I'm only using the demo but I would think it should behave very similarly. Our specs are nearly the same so I tried everything you said. I went back down to 182.50, disabled v-sync only, used the command line switch '-maxmem=2047 -winxp', removed the .cfg file... didn't help. I get 20-30 fps on the intro menu, and between 30-40 fps in-game.

When I run the benchmark in the demo it says my average fps is 25.

Here are my specs:

Intel Core i7 920 (3.8 GHz)

6 GB OCZ Platinum DDR3 (1600 MHz)

2x GTX 285 - SLI

2x 1.5 TB HDD - RAID 0

Windows Vista x64

1920x1200

In-game settings:

Visibility: 3600

Quality preference: Very high

Interface resolution: 1920x1200x32

3D resolution: 1920x1200

Texture detail: Very high

Video memory: Very high

Anisotropic filtering: Very high

Antialiasing: Very high

Terrain detail: Very high

Objects detail: Very high

Shadow detail: Very high

Postprocess effects: Very high

Interface size: Very small

Aspect ratio: Very high

I've turned down various settings, and the improvement is negligble. When I've set everything to Normal instead of High/Very high, the average fps in the demo's benchmark only goes up to 34. That's not acceptable for my computer.

Also, in case anyone is wondering, my computer has brand new HDD's that I just put into RAID 0, meaning this a clean Windows install, and only the basic essentials run in the background.
