Way to cap framerate without v-sync or capping at framerates higher than 60?

[Platsys]

Something thats been really bothering me about the steam deck is V-sync is forced on in game mode, this works really well for some games but for others the input lag is atrocious.

You could use steams uncapped framerate mode, and that does make some games feel way better, but then if your playing something like Rogue Legacy the framerate shoots to like 300fps, makes the fans get louder, and decimates your battery life.

Are there any tools similar to something like Rivatuner on windows that would allow me to cap games to arbitrary framerates, maybe just straight up running Rivatuner through proton?

You have MangoHud & Gamescope installed already
Don't they do that?

dxvk can limit fps with a launch option. how would a windows-specific configuration software work on Linux? native solutions are the only way in this case.

Wait is Mangohud installed by default? If that's true how do I use it? I tried using the flatpak version and it worked, but I couldn't figure out how to change its settings so that it would cap your framerate

Is dxvk installed by default or do I have to go to the github and download from there?

And what command would I need to, say cap the framerate at 120fps?

dxvk is part of Proton, installed by default (it's responsible for translating DirectX graphics instructions from the game into Vulkan instructions that linux gpus support) but only usable for windows games, not linux native ones

MangoHUD might do the trick for linux-native vulkan games, but not OpenGL ones

for those remaining cases, it's probably easy to use "libstrangle"

all 3 will require setting some game launch parameter in the game preferences in the library to actually to leverage their frame-limiting capabilities in some game

libstrangle might also need to be installed before using, I'm not sure if it's preinstalled

[Marlock]

try this:

DXVK_FRAME_RATE=120 %command%

just found this:

Command worked perfectly thank you! will check out that reddit post in a bit as well, seems useful

tried the command with elden ring but at 30fps and it did not work for some reason ):

is Elden Ring using DirectX 12? DXVK is only used up to 11.

Elden Ring is a DirectX 12 game. vkd3d "translates" Direct3D 12 instructions for Vulkan. MangoHUD should do the trick.

Try the following launch parameter:

MANGOHUD=1 MANGOHUD_CONFIG=fps_limit=30 %command%

Worked perfectly! But is there a way to disable mangohuds, hud?

[Marlock]

if you mean forcing it off for a game when you start running it, MANGOHUD=0 instead of =1 maybe?

if you mean hiding its visible elements while still using it to control fps...

Is it possible to change Mangohud settings while the game is running? #399
...
A lot of settings can be changed while the game is running edit the config file and save it and it should reload.

[Marlock]

better yet, add this to the game launch parameters:

MANGOHUD_CONFIG=no_display
