At work PC, will add picture later.
But I had Eth0's Plastic Hawken on with physx checked on (with radeon card) and Graphics and textures set to low for super plastic mode. Then i put textures up to medium (with graphics still at low, physx on) and Hawken turned into a wonderful magical place.
Colors danced around the walls and trim or equipment. Paint on peoples mechs would sometimes flash brilliant colors. Its awesome. I highly suggest it. Someone needs to do it and post a video.
