Thanks!I've already used the fsx.cfg tweak tool to great effect but so far as I understand, the Shader Model 3 only works in DX9? I'm using DX10 as FPS is better. Would switching back to DX9 and using Shader be better?

Hi AllMy current visuals machine employs an ATI 5770HD card to provide front left, front and front right views on three monitors. I suffer from a massive fps drop whenever I introduce any more than a slight scatter of clouds into the mix. In clear skies I get 40+ FPS. Anymore than a very slight scattering of clouds and this drops to about 16FPS. To my knowledge I cant use and external FPS limiter as I'm using DX10 (massive fps increase over DX9 for me). On a single monitor I can max the weather and still have great performance. I expect a drop when using Eyefinity due to the increase in resolution.I have read that ATI cards don't tend to handle clouds that well so my question is; Could I switch to 2 x Nvidia cards in a SLI formation (to continue with 3 monitors on one machine) and not suffer such a severe FPS drop?Info on the whole setup can be found in my blog (below)RegardsAlexwww.al3x-foster.tumblr.com
