genus VS goverlay

One of the games using it: https://github.com/ModusCreateOrg/genus

There's probably a million different ways to limit FPS. I use GOverlay as a front-end for MangoHud, and limiting FPS in it is extremely simple. Simply change "FPS Limit", Save, and you're good to go. Use the selected hotkey (F1-F4) to enable/disable the limiter (and right shift + F12 to show/hide MangoHud itself)

Many people seem to use GOverlay as a GUI to configure it. I do it manually because when I tried GOverlay long ago it wasn't ready yet, but maybe it's good now, try it if you prefer a GUI.

I was just clicking the icon in the application menu but it wouldn't launch. However I came across the issue in Github: https://github.com/benjamimgois-zz/goverlay/issues/203 , I used the .deb file as suggested and i'm able to use the program again.

Currently, the best workaround seems to be installing an older version. You can find version 0.6.1 here, (PPA linked by the GitHub page of GOverlay). Download the deb file for Impish, and install from file with apt.

Mangohud supports temperatues and all other infos you'll need. check out goverlay on github here

GOverlay is a GUI application that can be used to manage the config

If you don't like configuring it from config files, there is a great GUI for configuring vkBasalt and Mangohud called GOverlay, available here. Sharpening is under the vkBasalt section's CAS tab.

Would be interesting to see what the deck would look like with Reshade's fakeHDR or other options. Even the fakeHDR option makes a big difference in contrast and vibrancy. On Linux Reshade is called vkBasalt and can be configured with gOverlay. Don't know if that's available already via SteamOS.
