On long rides I often Zwift and watch TV/a movie at the same time (2 screens).
Previously this was never an issue but at some point in the last few months it’s started maxing out my GPU and I get jerkiness/screen issues on the movie (I don’t mind Zwift being a bit stuttery as I’m not really looking at that so much).
Looking with task manager I can see that the VRAM on my GPU (3Gb) has been filled and it’s starting to use system RAM, and “3D” and “Video Decode” are both up near 100%.
Interestingly if I start the movie before loading Zwift it’s sometimes OK for a while (I’m assuming it means that the movie player gets access to the faster VRAM and Zwift ends up partially in system RAM).
Machine is Pentium Gold G5400, 8Gb, NVidia 1060 3Gb, running Windows 10
I do have a 4Gb NVidia 970 in another machine I could potentially swap if it’s likely more VRAM might help.
It’s running “Ultra” profile at 1080, but reducing resolution to 576 in settings, or replacing the “Ultra” config with the “Basic” one doesn’t seem to help.
Does anyone have any other suggestions? I appreciate this may not be a RAM issue so grateful for any hints. Thanks!
