SUBSIM Radio Room Forums - View Single Post - Bug in DW when using SLI Multi GPU mode on Nvidia Cards

Just bought a really great system last week, and also bought DW finally.

I have an SLI motherboard with 2 Geforce 7800 GT video cards.

For those who don't know, SLI allows 2 video cards to be used on the same monitor, and can increase performance up to 100 percent. So in my case, I in effect have 512mb of Vram, plus 2 video processors.

However, in case some are having trouble, for DW in the Nvidia config you must use SLI single GPU rendering (in the advanced settings). Using multi GPU rendering (really what SLI is for) causes all sorts of screen corruprions. Text is flickered and unreadable, and pop up menus (such as the weapons, navigation, and other toolbars) rarely show up, and when they do they flicker in and out.

Just thought I'd pass this along. I discovered it today after downloading a bunch of mods, thought I'd buggered my installation. Reinstalled and found the problem still existed, but creating a DW only profile with SLI single GPU renderiing solved it.
