I have just installed OpenRCT2 on my Mac (late 2013 Retina, 2ghz i7, 8gb 1600mhz ddr3, Intel Iris pro 1536mb)
v0.2.3 "Tim the Enchanter
I can't get the game to run playable, the frame-rate is so low, everything moves jerky. I tried lowering the resolution, bus this barely helps. Even on the lowest settings, my Mac immediately starts cooling. What can I do or check?
I installed the game by downloading it from GOG, installing it via Parallels and copying files to my personal Mac programs folder.
