Quakespasm Engine
This engine needs its own thread.

Feedback: I like the OS X version, but I have to start it from the terminal for it to work and can't just double-click it like a traditional OS X app. I'm sure you guys already know this, either way great engine.

Elevators Etc. Working Funny Past Host_maxpfs 165 
Hi!

Thanks for all the hard work you've put on this great engine. It wasn't until now that I was able to come across a bug that I'd like to report.

Fairly recently I got myself a monitor with a max refresh rate of 165 Hz, so to squeeze out all that juicy smoothness the monitor can offer, I decided to adjust the host_maxfps setting in the config to 200. However, this causes problems that can be seen most notably in elevators: all entities onboard the elevator seem to kind of lag behind.

For example, if I go down an elevator, the elevator goes down smoothly, but I go down in skips, as if I was Wile E. Coyote forgetting that gravity exists for a split second and then I fall on the elevator again only to forget gravity for another instant as soon as I touch the elevator again. And the pattern repeats.

The same happens going upward, with more severe consequences, as I end up slightly inside the elevator, which may sometimes cause the elevator to think that it's squishing me, which causes it to damage me and then reverse back down.

I did some testing, and the only influencing factor seems to be the value of the host_maxfps setting. (Fiddling with the V-sync settings didn't seem to do anything.) The threshold value seems to be about 165, above which the problem starts appearing.

Anybody else have this problem? Sorry, if this has been addressed before.
