View Full Version : Slight SLI Problem...

Hi all first post,

Usually I never have a problem with any games and my gaming rig, so far everything just works. I run an internet box so my gaming rig only has windows xp sp2 installed and no other updates, no virus protection, no extraneous crap whatsoever and seems to be the key to smooth gaming.

All the latest games such as Stalker, GRAW2, Oblivion, DIRT, run great at max settings (cept for medium shadows in DIRT).

Cept this slight problem haha,

Something I have noticed recently and its starting to bug me is an issue with what seems to be SLI and looking around with the mouse in an FPS.

I have 2x7900GTX's in SLI and while I seem to be getting good frames especially when moving forwards and backwards or even strafing left and right with the WASD keys (seems smooth) often when I turn the mouse in these situations seems a little jerky.

I never really noticed it before until I accidentally ran a game that used to run in SLI in single gpu mode for a while and then switched back. Even though I had less frames, the left, right, up, down view when moving the mouse seems somehow much smoother or something.

I remember reading something about this like last year maybe? Is there possibly a drivers setting or some tricky workaround?

Thank you for your consideration.

You mean something like mouse lag ?
i had a bunch of talk about this issue last year.

I guess, thanks for the links. If 'mouse lag' means a slight jitteryness then yes, although the word 'lag' to me means a delayed reaction, as in the mouse response is not immediate which is not really what I am talking about.

Was there ever a definitive solution posted for this?

there is no solution... thats just the way SLI is... also the faster your CPU the less lag/jerkyness youll get but even with my E6400 @ 3.5GHZ i still notice quite a bit of in... some games more than others... one really bad one would be oblivion

Exactly^
this is how SLI works for the time being , it may get improved with the time & technology (& software perhaps DX10 , 10.1 or 11).
thats one of the reasons that made me abandon SLI , unfortunately.
