F Train fan, what are your specs? You don't see many computers weaker than a Pentium III and 512 MB of RAM these days (which are the minimum specs)
it's actually the graphics card the R46 depends on. Actually, the bare minimum for a playable R46 is a Core 2 Duo, 2.4GHz or higher, and a 256MB ATI/AMD or NVIDIA graphics card.
