3-way SLI & Surround

Post » Tue Sep 14, 2010 4:49 pm

Hey there,

I just wanted to check if there is anybody else that also has a 3-way SLI system and utilizes surround (3-screens)?

For some reason in this game, even with 40-70fps on a resolution of 5760x1080 I have lag. Seems to be input-lag. There are no problems with regular SLI and I don't suffer from any flickering that others reported and the game runs perfectly fine with 100-300fps on extreme with 1920x1080.

Anyways, I've already tried (with the latest EVGA SLI enhancement patch) to edit the Crysis2 profile, changing it to pre-render less frames, making sure v-sync and triple-buffer are off, but to no avail.

It's really annoying to know that your system is build for this, but the game just won't let you utilize it, unless you wanna get motion sickness or something.

I should probably also note that while many videos run nicely on the center-screen (being aligned to height I assume), there are plenty of sequences (like the ones at the end of a level, before the loading screen) that are actually scaled according to width, making me lose the top and bottom third. It would be better to have it scale according to height of resolution so it centers on the main/middle screen.

Nonetheless, I'd much rather solve the input-delay/lag issue when utilizing surround/3-screen resolutions. Any advise?

I take it, there aren't a lot of geeks around here. Weird... nVIDIA doesn't seem to wanna respond to issues with surround either.

Well have you checked to see if it runs fine with 3 cards + 1 screen or 1 card + 1 screen?

Yeah... like I wrote: regular SLI works fine... that is 3 cards on 1 screen, getting 100~300fps. Even 2 cards (by making 3rd card dedicated to physX) on 1 screen. All fine. None of the flickering issues either. It's only 3 screens that cause input-lag.

I also have no problems with single-card on single screen... as that's what I use when recording with fraps. Fraps doesn't seem to like 3way SLI for some reason :(.

MultiGPU isn't supported yet. To bad for me but I can disable Crossfire for now. Saddens me more for the people with HDxxx-x2 video cards so not only SLI for NVidia. They patch it up soon I hope.

Multi-GPU works perfectly fine people. Dunno about ATI, but for nVIDIA all you need is a new SLI profile. The EVGA SLI-Enhancement pack will do that. I'm talking about 3 screens, surround gaming. 3x 1920x1080. That's what's causing input-delay/lag. Single-screen, but with SLI (or without) works perfectly fine. I'm not even having frame-rate issues on 3x 1920x1080. 40-70fps maxed. It's just that every move I make with mouse or keyboard simply comes with a delay on screen. A noticeable delay.
