Better in-game frame limit options to encourage the use of VRR

[Spok5508]

VRR is great especially for lazer's multithreaded behaviour.

As it currently stands, none of the in-game frame limiting options are optimal together with freesync/gsync.
It's a widely accepted concept that capping your refresh rate around 0.3ms under your max refresh rate is optimal when using g-sync.

Currently, the best way of going about achieving this is to use the direct3d renderer and set ultra low latency in nvidia control panel, this will automatically cap the game's framerate to the optimal scenario for gsync to work.

However, using OpenGL, users are stuck using a third party frame limiter for this scenario to work well at all.

Third party frame limiters will always introduce more latency compared to in-engine ones, so I'm suggesting there be an option in-game that can enable vrr users to cap their framerates in order to get the best experience possible. I'm also not fond of the idea that players have to rely on any third party programs to get the best gameplay experience, especially when the solution is as simple as adding another frame limiter option.

nvidia reflex could also be a solution to this, as it will cap your frame rate optimally in conjunction with gsync.

It's a widely accepted concept that capping your refresh rate around 0.3ms under your max refresh rate is optimal when using g-sync.

This is under optimal conditions and can go very wrong. I would never offer this as general advice or add a limiter specifically for this. The best you'll get is something like stable where you can choose your limit Hz manually, then it's on you for setting silly settings.

But I think the bigger picture is that we just need better support for things like nvidia reflex, which will offer larger gains.

Yes, and reflex in this scenario will also cap your framerate below your maximum refresh rate (e.g on a 240hz monitor using gsync, reflex will cap the framerate at 224fps). When the framerate exceeds this gsync range, it can introduce additional display latency and that's why reflex also does this.

Whether it's reflex or some other in-game vrr specific frame limiting methods, I'm just suggesting that lazer helps enable the user to get the best possible VRR experience, as a lot of people don't have a clue on how to set it up correctly.
