VMware Fusion it has accelerated display drivers... and afaict all my first person shooters actually have *HIGHER* frame rates in Fusion (even yes v1.x that I have) than was on the nVidia card I had in the Athlon64 3500+ (GeForce FX 5200 (NV34))
OpenGL perfs are Great, DirectX (whatever version is on my VM) and much other stuff just has ungodly frame rates. (45+ FPS) at most resolutions above 1280x1024.
So, you fail on that line of reasoning.
I literally have *ZERO* performance on video anything in Fusion (nor did I in VMware Workstation for Linux). I don't see your complaint.
Sure Crysis at max resolution and AA and everything enabled SUCKS on everything though... baremetal or not.
If you want a UNIVERSAL machine... PICK ONE and go there. Stop footing around with all of them. PICK ONE AND GO THERE.
I know its easy to say... but I've done it. You are like a crack addict that won't leave it alone. I only have WindowXP on the machine for demonstrable Windows and my Wife's Govt required Daycare reporting application written in Access with remote calls to a "secure" internet DB. (yeah I know) and mainly for her.
