Puzzled by games crashing when using second gfx card for PhysX
Recently my 4870 X2 failed and as I had a GT240 laying around I put that in until I could get a better card. I then purchased a GTX 460 Cyclone and ran that with the GT 240 as a dedicated PhysX card.
I started up Fallout 3 and it started having random crashes on average about every 35-40 minutes. I tried New Vegas and the same thing. I had been able to run both games with almost no crashes using my 4870 X2.
I tried various drivers thinking there might be a bug but crashing continued.
The only thing I could think that was different was having a second card for PhysX, So I removed it and now both F3 and NV are running as stable as they were on my old 4870 X2 (RIP).
So my question is, why would using the 240 for PhysX cause the Fallout games to randomly crash? Hope you can help as this is really puzzling me and I am also wondering if this will happen if I use a second 460 in SLI.
