Two days ago I was at my AMD PC (only the GPU is made by AMD) and I updated to the latest version of Action! (1.24.1.0) and started to record some Elite: Dangerous footage in my Oculus Rift DK2.
I played on the lowest possible settings (Oculus Rift is a really demanding gadget, you're basically playing on two digital screens) so that I could get the least amount of juddering, and the gameplay was pretty good.
When I went back to normal mode and exited the game, I saw that Action! still hadn't fixed the 50 FPS "variable framerate" thingy, but that's not too big of a deal, I thought.
But yesterday when I got on to my Nvidia PC and did the very same thing with the very same graphics settings, on a less powerful PC, it converted it to 60 FPS flawlessly (even though the gameplay mostly ditched below 60 FPS).
I think you guys should look into this.
