A glance back into Ghost Dog history with Infiltration:

Well, I think Inf is dead. And the UT3 engine isn't much better.
Next best bet is probably the OE2 mod for Crysis.

Well, it's actually easy - unless you're one of the alleged 50% that don't get it running at all. If you're in the lucky 50% (i.e. those that get it running) you'll probably just have some speed, driver, sound and GPF problems en route..I wonder how much i would hafta do to get this running under vista.
I mentioned it before [in the support section I think] and I'll mention it again: I found RightMark (http://cpu.rightmark.org/) to be a really nice tool for this [and other applications] since it allows you to actually select which speed your CPU runs at and not just forces the CPU to maximum speed. Inf doesn't really need maximum CPU speed anyway, plus if UT/Inf runs at a too high framerate you end up having game speed problems again - it's some kind of vicious circle..but there are a couple of progs out there that force your CPU to run at full power..
