Add a max FPS limit control to the options menu

What version did the issue occur in?

Description

Apparently some GPUs don't understand the concept of moderation without the game you're playing telling them there's a frame-per-second limit. Mine are apparently in this category.

With Vsync turned off and in full-screen mode my GPUs push themselves into their non-overclocked limit and in doing so spiking their energy draw, heat to about 70 Celsius, and make a massive amount of hellish noise.

I strongly request the addition of an alternative frame limit should Vsync be disabled as this can and will go so far as to physically damage the computers of the unaware and unprepared.
(Some people play on toasters and they shouldn't suffer this for doing so)

Reproduction

1. Have a GPU that doesn't have a specific built-in limit just for this. (Thanks Nividia)
2. Play on any server in fullscreen with Vsync off
3. Cover your ears from the infernal screams

Additional Context

I only realized this was a universal thing to all servers recently when I turned Vsync off and went to test if it was just the one.
On the plus side; my computer took it like a champ apparently. It seems like there's no damage aside from possibly my hearing.

Apparently there was a post on Discord about this exact issue back in 2024 that just never made its way to Git.
There may have been similar reports of this. If there are then I couldn't find them; I am not very familiar with Github in general.
Either way, since then everyone that has the issue has collectively decided to just use Vsync.

fps limit already exists, see display.max_fps cvar

This is arcane to me. Where do I find this in the settings?

[mirrorcult]

you can set it ingame by opening the console (`) and using the cvar command, i.e. cvar display.max_fps (whatever fps limit)

Okay! This certainly works and is effective.

Would it be possible to have this set to a baseline of some sort to prevent those unaware of it from hitting 700 fps?
Also maybe giving it a UI element in the game options menu as a longer term goal?
