Summary0005464: TDM 2.08-2.09 beta 1: uncapped FPS causing weird player physics
DescriptionIf I have uncapped FPS enabled and max frame set to 400 two issues occur -

1. you wont reliable and consistently hear player footsteps while walking.
2. if the player jumps in the air they will hang there in the air for 0.5-1 seconds if the space key is kept pressed.

In you enable vsync or turn off uncapped FPS both of the above issues will resolve themselves.

TagsNo tags attached.

Update to this issue, Iv'e been told by Duzenko/Stgatilov not to have the FPS limit set to anything higher than 300. I can confirm this then fixes the issue.

It might be worth setting the max limit to 300 by default for 2.11.

Rev 16595

Altered the GUI to only offer 300 FPS as the highest value.

Well I was going to upgrade to a 360hz/480hz monitor next year :(

@AluminumHaste, Jokes aside once you get above 144hz the average gamer isnt going to notice the difference. That and even once the 4090 hits retail your still not going to see high FPS coupled with resolution above 3440*1440p in the majority of AAA and even AA games.

Oh for sure, those monitors are limited to 1080p, the current DP/HDMi standard can't even serve that much bandwidth without compression.
Going to need a new GPU just to use a 480hz display.
But, technology marches on, it always does. And in 10 years time, people with 1000hz displays are going to notice stuttering because games are capped.

Dumb question though, is there a way to just limit physics updates based on time instead of fps? Do we really need more than a certain amount of updates a second for physics? Can physics updates be capped at 5 ms? Or does checking time from last update cost too much?
