For uncapping the framerate
Go to <path-to-game>\GameData\indy\
Open vars.cfg with a text editor.
Change fpsLimit=30 to fpsLimit=60.
I recommend setting the limit to 59 (just a tad lower), rule of thumb is when playing old games to never exceed 60fps a lot of problems arise when doing so in my experience.
I played and finished the game with a 60fps cap and didn't have any problems, others who have uncapped (200+ fps) it completely caused the game to bug out in certain sections
Hope you have fun playing, this game is one of my favorites!
