I already disabled GLSL because the game wouldn't even open with it on.
I know Intel has a lot of problems, but I had it working perfectly for over a year, and now suddenly its not working.
Grass and weather are disabled, shaders are on lowest, textures on low, particles on medium (because that's apparently as low as they go). Could it have something to do with water reflection? Maybe rending far-off pools of water is what's causing the crash.
