Just more a quick heads-up in case it's useful to anyone, get it on searchable record etc...
Using an ATI 6870 [in part because that was what they initially tested 11 Pro with], GPU accel on, with an i7 CPU on a Z68 m/board with Intel graphics & Virtu on in Discrete mode. That's what's gotten me the fastest encodes using Vegas Pro 11 64 & the Sony AVC encoder set to Auto.
Tried adding the Intel OpenCL drivers, basically just to see what would happen. MC mpg2 encoding *may* have *slightly* sped up a bit, but Sony AVC was missing from the render dialog -- 64 bit Vegas Pro Only. Disabling Virtu &/or Vegas Pro GPU accel have no effect. Renaming/disabling IntelOpenCL64.dll in the system folder brought the AVC encoder back.
My *guess* is that when the Render dialog 1st opens it checks for avail. encoders, the Sony AVC encoder checks for graphics hardware it might use, & dies when it gets to the Intel OpenCL. I did not check or investigate further -- it was just a quick experiment after all. :)
