My PC has a Ryzen 5600X and RTX 3080 Ti. After installing the LSFG-VK plugin, when I enter the game with x2 scaling, I see the frame rate double in Gamescope, but the actual visual effect doesn’t take effect. What could be the reason? I’ve already tried enabling ‘Disable Frame Rate Limiter’ and ‘Allow Tearing’.
Hi. You must buy and have installed Lossless Scaling from steam first, then in its option go to Beta e activate the Linux beta version.
Only now this plugin will work. From my experience, it works best with disabled frame limiter, allow tearing, enable fsr on sharp (somehow it locks correctly frame time and vsync, don’t know why) and limit the framerate either ingame or with this plugin at the half if your monitor refresh rate, then set it to x2.
Im using it like this with borderlands 4, works perfectly. Hope this was helpful 
Thank you for your response. I have already tried installing Lossless Scaling, then selecting Beta in its options and activating the Linux beta version, disabling the frame rate limiter, allowing screen tearing, but I haven’t yet tried limiting the frame rate to half of the monitor’s refresh rate, then setting it to 2x and enabling the sharpening mode’s frame rate adjustment。
