Okay, I'll answer the ones I know. In all of the options above, the better the settings, the worse the FPS. SO..... Anisotropic filtering is better than Bilinear or Trilinear, and Full HDR is better than Bloom. As for Heapsize, I've no idea. It should be mentioned that with NVidia GFX cards, it is not possible to have HDR and AntiAliasing on at the same time. It is, however, possible with the new ATI cards. And while a higher refresh rate isn't "better" per say, it is a bit better if you have a CRT with regards to getting headaches! If you have a LCD, it makes no difference.
