3D graphic performance

Hi to all,
I am using Parallels to run Matlab (a program for numerical calculations) on Windows, since the OS X version of the program is much slower. I have run a benchmark and noticed that the 3D graphical performance of the program is not good: when the vm is run in its separate window or in full screen, it runs at approximately 20% of the speed at which it runs on Windows installed in the Bootcamp partition (same program, same operating system, same machine, only difference virtualized versus native); the interesting part is that if I switch the VM to coherence then the graphical performance improves drastically, and returns closer to the "native" performance. I have already checked what was obvious to me (and maybe it is even not relevant), that is that a lot of memory was reserved for the virtual machine (the one for graphics seems to go only up to 64 Mb though). Could someone explain to me this behaviour? Thanks in advance,

Giovanni
 
You're saying that 3D apps can run faster in coherence mode!?

How come there is no mention of this anywhere else?? This means I could be running my 3D apps faster than I am, this is an unannounced benefit and everybody loses from being unannounced. :/
 
Some 3d games require full screen, others you can use, just be aware that in some 3d applications may be memory leak, which can cause problems in Coherence
