Cheers, not tried the omega ones yet, been fiddling with a few more settings. I've now turned the effects settings to "off", and suddenly its like a different game! With the default high settings and effects off I'm getting 20-30 fps consistently, and now on the low settings with effects of it's running at 30 to 60+ !?!? Still, hopefully I can now get on with the game a bit more! Lawn darts anyone?
