Hi,
I have looked around and I can't seem to find a solution for this. This is not an issue with OBS, since XSplit produces the same issue.
I am running GTA:VC through Steam, running at 1920x1080x32 fullscreen. The game runs fine on my end at 60FPS. However, both OBS and XSplit seem to pick it up at a lower FPS. I can't tell what FPS it is, but probably something around 20. The FPS is consistent, so it seems to be capped. Other games seem to be captured alright, such as SC2, which captures at full 60FPS.
Has anyone else come across this issue in other games? Perhaps GTA:VC uses some rendering method that causes capture issues, but I have seen other people streaming GTA:VC just fine, so perhaps just the Steam version?
If anyone could shed even a single ray of light on this, I would be grateful. Thanks. I can do a recording on Twitch if you need to actually see it, but I hope I explained it well enough.
EDIT:
Here is a log:
