turning off GPU in 11 a fix for earlier versions?

This may be a premature post (been guilty of that before) but I'd like to ask members if anyone else has found that switching GPU accel off in V 11 fixes some issues with earlier versions becoming "broken" after installing 11 (in my case 9 & 10)

Turning off GPU acceleration in 11 has (at least with my first three tests) fixed one of my issues with previous installations. I can now modify Sony AVC rendering templates in versions 9 & 10 and render to several different bit rates without a crash. Prior to turning off GPU acceleration I have not been able to do this for over a week. Any modification to a exisiting template always resulted in a crash in 9 or 10.

I've been burned too often by thinking I had discovered something only to find that it was a fluke, so I'm going to keep testing for several days in a regular workflow to see if this holds true. IF this is a simple fix for previous versions (at least in the rendering arena) then it appears that V 11's GPU accel switch is either modifying a registry key or some global .ini that is passed down to other versions.

And I hadn't considered it before but possibly the change that is being made involves a GPU file or registry key. I'm going to examine those files and keys also.

I'll also ask, has anyone who does NOT have an acceleration-supported GPU experienced problems with old versions of Vegas not behaving properly?

Thanks,
Larry

It fixes at least two issues for me: pan+rotate for JPG picture messing up and using a particular Video FX that messes up. Both problems go away when I turn GPU Acceleration OFF. I have a Dell laptop M1730 with NVIDIA GeForce 8800M GTX video card.

I assumed people who had problems tried turning off the GPU support.

It would make sense, wouldn't it. My logic fails me on a regular basis, though. It took me a while to get my head around the fact that Installing 11 had actually broken earlier versions. I kept looking for other causes.

11 was performing great for me with GPU accel on (except for the universally noted bugs) no crashes. V 9 & 10 had no performance issues in editing. Wasn't until I tried to render Sony AVC in 9 and 10 that I found things were different than before.
