flashpmp, that was a pretty poor response, also not unexpected based on my support experience. I think one needs to get past the level zero queue card support desk but I'm not the CL elite with badge and direct RD hotline. I won't try and dissect entire response but I believe maybe it's outlining min requirements, i.e. at least the 2nd gen (Sandy Bridge) CPU or newer, at least a MB with Intel H67 chipset or newer.....
My testing was with a MB with Intel Z77 Express chipset and a Ivy bridge 3770, Win7 and Intel GPU encoding is totally functional so they didn't skip the Ivy. As I indicated, depending on the task at hand and timeline complexity, typically 45-85% GPU utilization.
If you desire, I'm still glad to run several sample videos in the retail version of PD12 and convert with Intel GPU to what ever format you would like for your encode time comparison.
