Go to Config > 3D Settings > 3D Rendering Engine > OpenGL 3.2
Then under General Options pick GPU Scaling Factor (2x is fine enough, 4x is overkill)
Finally if you want to smooth the textures choose Texture Scaling 4x and under OpenGL choose Multisample Antialiasing (32x works best) and tick the box next to Smooth Textures.
If you get slowdowns somehow (you shouldn't) try skipping up tp 4 frames. Go to Config > Frame Skip
check Limit framerate and Auto-minimize skipping then choose the number you want.
