I'm not sure why this issue exists, but I am having issues with frame rate on the RO steam client. When I play the game for an extended period of time (more than 5-10 minutes) the frame rate slowly starts to drop to about 10-15fps. I checked if there was a memory leak and there doesn't seem to be. This happens cpu usage and memory usage are below 30%.
I do not have this problem at all when playing the game through a nonsteam account by launching the program from the Steam application folder. This makes the game on my Steam account virtually unplayable for any extended period of time. Anyone have an idea what's causing this?
