Thanks for the advice Paul!But the 'shaders'-folder didn't exist tho, so I installed the Shader3-mod:No changes.I took a look through the FSX.cfg and deleted the new [bufferpools]-section:Works!But as noone else seems to be having such problems, I suppose these problems appear because I'm using theun-recommended ATI Radeon X1300/1550.I'll just stay with the FSX.cfg now (seemingly the [bufferpools]-section doesn't affect ATI-cards too much anyway :()
