SLI FPS vs Single card FPS

post #1 of 53
Thread Starter 
is it just me or does anyone else felt like their fps in SLI scales lower than single card sli??

for example 80fps in sli feels like 50fps in a single card... when i play bc2, when there's something heavy such as explosions and stuff.. my fps goes down to around 80-ish.. but the thing is that it feels like 50fps lol...

Have your eyes checked maybe. When it says 80 FPS it's probably 80 FPS.

I run v sync to lock it at 60FPS and takes care of the stuttering/tearing also.

well.. yea the thing is that vsync feels the same.. but the weird thing is that the fps in sli mode tend to feel more stuttering in bc2 (and so far is bc2) under heavy scenes..

Might be the case if the SLI does Alternate Frame Rendering, as opposed to the split frame rendering. Microstuttering is exactly what it's called. Try to switch to split frame under nvidia driver settings.

Just played 2 rounds without vsync lowest I saw on a 32 man server full with smoke/explosions everywhere with fraps sucking back a few FPS was 93 at it's lowest 140ish just running around by myself. Something's up those cards should be owning my SLI 460's(everything maxed except 4XAA because of my tiny vram).

Problem is, you can't "feel" 80 FPS or even 70 FPS since your monitor is capped at 60 FPS unless it's a 120 Hz monitor anyway. BTW, you can't "feel" 50 FPS since your eye (piece of crap, I need to get a better pair of these) is "capped" at 24 FPS in terms of fluidity and it can simply pick-up more details with more FPS. Problem is, that's useless since most games use motion blur so that it looks more fluid.

Depend on what driver and what game:

here is SLI scaling between drivers:

you have the point.. but let me rephrase it.. not that i can "feel" it but i do noticed that the stuttering is kicking in.. the input response of my mouse tends to go down too.. kinda like when you turn on vsync and your input response goes down..
