Disable SLI?

???? should I disable SLI when I'm playing this or just leave it alone?

SLI did not exist in 2004, afaik, so you might have to disable it. But honestly, idk, just log on to some random vanilla server and see it for your self.

I don't think you need to disable SLI. However, you'll just have to try it and see

 

Easily controllable though so should not be a problem.

Actually it did, http://techreport.com/review/7671/nvidia-sli-in-action

 

@Gizzles2313, the simple answer is: yes it will work.

 

The more technical answer for dummies is, don't use it in a game as old as this one. Your PC should hopefully have zero issues rendering this game at +100 FPS so then we get into the area of input lag. For this version of WoW the drivers will resort purely to AFR. The issue with AFR is that "GPU one" starts rendering the next frame as "GPU two" is just about to finish his frame to put it on the backbuffer. Long before "GPU one" throws his frame on the backbuffer, "GPU Two" will already have started working on the frame after this one. This results in input lag caused by the fact that "GPU two" is now rendering a scene based on input that you had already given moments ago (mind you, we are talking in milliseconds here). So SLI, and the effect becomes worse as you add more GPUs to your SLI (or Crossfire) setup, adds a delay between the time of rendering a frame and the actual presentation of that frame. The problem in this case is that your cards will be waiting for the CPU to finish it works, while the GPU would already have been done rendering the next frame in a game as old (and simple) as vanilla WoW.

 

A visualization of this effect:

 

So the summary is, if you don't need SLI to get high framerates: just disable it. If you can't even reach >= 80 FPS without, then you probably want to turn it on.

SLI will work in fullscreen, probably wont in windowed-mode. If you leave it on or off is up to you.

I'm just going to disable it when I start playing. I noticed that when I watch the cinematics it goes nuts when SLI is enabled. when I turn it off its normal...Ill just turn this bad boy OFF when playing

I use 2x980ti's. WoW Vanilla runs fine for me. Never had any issues with it in WoW. So I can't see it being an issue for you.

You can literally run WoW on max off a 256MB card. I used to play on a old single-core Intel celeron @2GHz with a ATI 256mb card. So SLI is not needed.
