Could it be that in your new OS that you no longer have GPU accelerated effects because of your CS6 file "cuda_supported _cards.txt" file is missing your GT 710 listing? It is a pretty puny GPU with only 192 CUDA cores and DDR3 video RAM in today's world but maybe it did contribute something to the mix. If you relied on Microsoft for the driver you might want to try 368.81 from the nVidia site. If that does not work there also is the possibility that you may need an earlier version driver
How can I tell if it's using GPU? I do have the following, making me think this is not the main reason.
1. An older card, Radeon 5450 HD, worked
2. The same hardware set worked well in Windows 7
Can anyone post your driver version for nVidia card? I have tried 3 recent versions and none made any difference.
It's greyed out. So I only have software playback. This is probably OK as the hardware is decent enough for play back.
The place I need to see better speed is stabilization effect.
So add your GPU to the list in the file "cuda_supported_cards.txt"
The top of the list looks like this
GeForce GTX 285
GeForce GTX 470
GeForce GTX 570
GeForce GTX 580
GeForce GT 650M
GeForce GTX 765M
GeForce GTX 680
Add yours like this: GeForce GT 710
Save the file reopen CS6 and try seeing if you now have the option
Yeah, that made the option available. However, a quick test shown there is no difference in CPU utilization b/w software only and GPU accelerated. This is a bit strange.
Well at least you now have MPE GPU acceleration. Sorry I could not help solve your problem.
the core are running at only around 2 GHz while the max is 3.5 GHz
how are you seeing 2ghz? cpu-z? is it only happening in premiere and other programs are able to max out cpu usage and at 3.5ghz clock speed?
if its a premiere problem only then you might want to try testing some new projects with different media/codec types to see if any will get closer to max cpu usage. if that works then start adding in effects and timeline/project changes of the old projects, one at a time, to figure out what is causing the problem.
if no program is working properly it may be something with windows or hardware. there were some windows patches for the amd cpu's back with windows 7 i think, but windows 10 should have those. you could also check cpu temps to make sure its not thermal throttling.
It seems it's everything exception the AMD benchmark software. AMD overdrive is showing at least 20C thermal margin.
handbrake 64bit should be able to max all 8 cores and cpu-z or amd overdrive should show all cores at 3.5ghz. 32bit programs won't be able to use all 8 cores and will show around 20-40% usage. you may also want to check if you have the latest bios update for your motherboard.
