I'm having some fairly serious lag in the IVA with this mod, which seems fairly odd to me. I've played around with the graphics settings plenty and it has no impact on my FPS. My computer is 3.5ghz i7, a GTX 760 w/ 4gb of VRAM and 16gb of RAM. Performance shouldn't be an issue at all. Now I had an older computer with a i5 2.5, 4gb RAM and a GTX 250 and the mod ran FINE, I was getting ~60fps no issues. So it seems there's some sort of optimization issues going on and I'm not sure where. Are there any fixes for this currently, or does any one know a way to increase FPS using the IVA?
