Library recommendation?

Thanks for trying it out!

I just updated the game with a new version that checks if enough time has passed since the last frame in OpenGL mode. Could you please try if that makes it playable?

@JC_, thanks for your hints, however this game was originally written in 1998-2001, first intended for DOS, later I added a kind of "emulation" layer for Windows, internally it is still using 320x200 mode with a 256 color palette. I would do many things differently if I wrote the game from scratch now (and I'm working on Charlie III). But here I'm just trying to get my old game onto Steam.

BTW: during the game you can Ctrl+Shift+R to show the framerate.

Still same and I'm not sure if new version was downloaded, put some version info there. OpenGL shows around 350 FPS, DirectX 60 FPS.

When ran in OpenGL the gam is still way to fast. In OpenGL the game is actually running with 290 FPS while in DirectX the game is running nicely with 60 FPS.
So now either your waiting code doesn't work or there is an error somewhere in your math.
