if you wonder how bad it is
As far as I'm aware after effects doesn't have any bugs while rendering so try using that, I think it's better anyways
After Effects CC 2014 is what I use
OBS/OBS Studio has customization to record, try messing with settings in there to get good framerate,maybe try shadowplay if you have a nvidia gpu.
Or you can do what tyzi did, record fraps with like 1 fps and speed it up in ae/sv so you get 60fps 100% of the time
or just upgrade your pc
I think you're getting the red screen cause of the layers.
Often when i put something like magic bullet look sontop of twixtor it bugs out and gives me a red screen.
