Framerate (FPS) Limiter, we desperately need this...

Feature Request

FPS Limiter

I confirm:

• [x ] that I haven't found another request for this feature.
• [x ] that I have checked whether there are updates for my system available that
  contain this feature already.

Description

A framerate limiter that works would be nice because vsync type limiting solutions can cause massive lag when enabled, so limiting fps without the overhead is preferred.

Justification

Proton is focused on Vulkan, vulkan as of yet has no unified fps limiter which is a preferred method of reducing FPS in order to save GPU's from overheating and also reduce tearing, it works like vsync but without the horrendous overheads that is sometimes seen with sync methods (ie. fps cost or control lag).

There is libstrangle which needs updating to work with newer vulkan functions like vKGetInstanceProcAddr (assuming). https://gitlab.com/torkel104/libstrangle

Risks

Proton would be at risk of becoming awesome :)

The issue names no Proton files, tests, or entry points. Start by reviewing Proton's Vulkan integration and the referenced libstrangle project; completion would require an agreed implementation and a demonstrated FPS limiter without the cited synchronization overhead.
