Yuzu performance drops when in fullscreen and windows 1080p etc..

Does anyone have the same symptoms as me? YUZU VULKAN suffers from performance degradation in 1080P windows and full screen. Curiously, maximizing the window returns the original performance. I am using GTX1080 and driver version 511.23 (I tried the latest version but the result is the same) And I added YUZU in nvidia control panel and turned on sync and triple buffering, but in the end it's the same.

do you have a gsync or freesync capable monitor?

yes. my monitor is freesync

That can attribute to this kind of issue then. If you have ability to disable gsync-freesync that would be ideal for yuzu. Otherwise the workaround was like changing app focus or alt tabbing?

It is the same with App Focus and Alt+Tap. I changed the alt+tab and focus a lot to take a screenshot from the beginning.

If you can then try disabling the feature. Gsync and freesync have been odd for yuzu for a long time now.

If you can disable it'll help you narrow down if it is the culprit or not.

What function is disabled? freesync? I turned off FreeSync. But the result is the same.

I found the problem. It was because of the reshade. If I don't use reshade, it works fine, but when I use reshade, the frame drops in fullscreen and window size. Interestingly, it shows the above symptoms even before applying the re-shade effect. and to test this It must be a game that requires high specs such as xc3. That way you'll know if there's a performance hit. yuzu_log.txt.old_no reshdae.txt yuzu_log_reshade.txt

Interesting. At least you narrowed it down! I know some Reshade presets can bog down some heavier pc games so it wouldn't shock if it did similar with some heavy yuzu games.

I found the cause of the performance degradation even before applying the reshade effect. It no longer causes fps degradation when "generic depth" is turned off. Now i can freely use the reshade effect. 2022-08-13 17 24 42
