Hey everyone!
I'll try to make this as short as possible, so...
I'm using the downgraded Steam version of the game. I used this tool (http://gtaforums.com/topic/753764-relsasteam-downgrader/) to downgrade.
Originally, I wanted to use DXWnd but since I couldn't get the mouse to work with it, I decided to play normally (fullscreen).
Before I had set up OBS, I didn't have any issues regarding framerate.
So then I set up everything I needed to start streaming, started up the game and got around 10 fps. Wondering if it was hardware-related and whether it would be the same in DXWnd, I tried using it and found out that I get 25 fps with it (60 without the frame limiter). I left the graphics settings the same.
Has anyone had similar issues? Does someone have an idea on how to resolve this?
Cheers, e216
