ToME: the Tales of Maj'Eyal

I'm not sure if this is the right forum for this, but the runner up was bugs and I believe the issue is on my end and not the fault of TOME's engine. I experience huge lag when an enemy confuses me (takes forever to even open a menu). I have lowered the particle effects value but the difference was marginal. Any suggestions?

My guess is that the screen-wide shader effect for confusion is consuming all of your computer's processing power. Check the shader settings in ToME (you may have to disable them), and your video card settings (you may need to upgrade your drivers).
