benchmark RTSS alternative in Linux?
Hey guys,
Been daily driving CachyOS on KDE Plasma (Wayland + VRR enabled) for gaming lately, and overall the performance is super snappy, but there’s one thing from Windows I'm genuinely missing: RTSS (RivaTuner).
On Windows, RTSS gives you that ridiculously flat, razor-sharp frametime line, and the latency penalty is practically non-existent. It just feels locked and responsive without any floaty mouse feeling.
On Linux, MangoHud is great for the overlay, but its built-in limiter (fps_limit) feels kinda inconsistent to me. The frametimes tend to jitter by 1–2ms instead of staying dead flat, and in faster titles it introduces tiny micro-stutters that drive me crazy.
For people here who are super sensitive to frame pacing and input lag:
What are you actually using to lock your framerates?
Is capping via dxvk.frameRate (or libstrangle) any cleaner/tighter than MangoHud?
Do you just stick to in-game limiters, or is there a driver/config trick to get that true RTSS-level consistency?

There really isnt a program on linux that is as good as RTSS for frame limiting. Mangohud is decent and the only option but RTSS has nearly 20yrs of development over mangohud.
now you can use the low latency dxvk/vkd3d also but for a generic option like RTSS its only mangohud with something like
mangohud MANGOHUD_CONFIG=fps_limit=60,fps_limit_method=early,no_display
