SLI & Minecraft
I have 2 GTS 450s, in SLI, works great for most games, but I cant find out how to get it working for minecraft (I use GLSL shaders, so its actually graphically demanding, like SSAO and so on, not to mention its in Java so everything is just poor and slow)
I've gotten it to split the load 50-50, but I cant get it to do anything beyond that. I'm only getting like 30fps, when I get flawless graphics in Battlefield 3 on Ultra. Anyone know how to get it working?

Yes SLI will work in Minecraft, i use this profile for Nvidia Inspector. The profile sets SLI and also forces 4X Multisampling & 8X Transparency Supersampling. If you wish to use FSAA, you have to keep the 8X SSAA. Using lower settings has visual glitches.

Just tried it, and it seems to have gotten my GPUs working at higher %s..
Except for one thing... It a little more than halved my FPS.
Now I only get 12 fps in Fullscreen.

Its also created some weird visual artifacts, like purple lines across water and green ones on grass, so on, mainly following the grid pattern of the game.

EDIT: Disabling AF removes artifacts.

But thats 0 performance gain from using one GPU....
