I monitor with MSI Afterburner. Temperatures stay well within tolerance levels-- around 60-65 degrees.
As I haven't changed anything with my hardware, and as other games don't have issues-- I can only conclude that there is some change perhaps in the patch that came with Jakku DLC, which has caused a conflict-- as I believe I also said I have tried rolling back to a driver that I know I was using previously without issue.
There doesn't seem to be any correlation between a lot going on onscreen, so it's not a case of video memory or loading/streaming stuttering, they are random freezes.
The VRAM usage always stays at about 5.1GB, and my card is a 6GB solution.
I'd like to thank you for the quick response.
