Almost every game I can run with a combination of 2x/4x internal resolution and/or 4x Rasterizer overclock, but Rayman 1 runs awful with all eye-candy off. Nothing seems to make it run over 40 fps.
cpu: 8250u, no dedicated GPU. But it runs other games well.
On a side note, I can’t seem to make both internal fps and effective fps to be viewable at the same time.
