Hi folks. Recently, I started replaying DOOM 3 with Sikkmod and texture packs (Wulfen + monoxead). With all the bells and whistles of Sikkmod enabled (HDR, soft shadows, bokeh DoF, SSAO, POM etc), visual quality is indeed quite nice. (Not amazing like some people claim it to be but overall nice visual upgrade from ugly original 2004 game). However, I find SLI scaling is horrible in this game. Average GPU usage hovers around like 10~15% only. (This is at 2560x1600 resolution) With frame rate dips well below 60fps with all those Sikkmod options enabled. In the end, I don't see any performance difference between single-GPU mode vs 4-GPU SLI mode. Is there a improved/updated/better SLI compatibility bits for DOOM 3 ??
