Patch for FPS Limit for Megaglest 3.5.2

[SnEptUne]

Hi people,

Here's the patch for limiting megaglest's FPS, since it would otherwise burn up my CPU.

Since I don't know how to attach file, I will just paste the content of the patch:

How can install it? Where should I paste this code?

This is a 'patch' or 'unified diff', produced by the GNU diff application. It requires a source code tree and the GNU patch application, followed by recompiling, to apply it.

Unless this tells you much, your best bet is to wait what softcoder and titi think about it and whether they consider the purpose of the patch and its quality sufficient for adding it to MegaGlest. If they do, it may be included in future MegaGlest builds starting with the next stable (and possibly development/alpha/beta) release.

Here's the patch for limiting megaglest's FPS, since it would otherwise burn up my CPU.

I'm trying to understand the problem this is solving;  something like your patch may indeed be useful to you.

What spec CPU and GPU do you have?

What OS do you use?

What FPS do you currently have?  (You can show this in-game using the ? key)

Indeed, I thought the FPS was amply self-limiting.
