Slow game speed until I click out of Yuzu window

Yuzu Support

Hi everyone - I’m totally new to Yuzu so I assume there must be something painfully obvious I’m missing. I did try to search the net and the forums for a fix but couldn’t find an exact match for this issue anywhere.

So as per the title, I’m experiencing a strange problem where Yuzu games run at a slow game speed after I load them, until I click out of the Yuzu window, at which point they will speed up to something more normal. I’ve experienced the issue with two titles so far - Zelda Skyward Sword HD (XCI file), and Xenoblade Chronicles 2 (NSP file). It seems to be consistent whenever I load a game (running Yuzu 1344 on Windows 11), and on both Vulkan and OpenGL APIs.

Although I am running the games at 2x standard resolution with High graphical accuracy, I think my system’s hardware is sufficient to handle this (CPU: Ryzen 5900X, GPU: Nvidia RTX 3090, 32GB DDR4 Ram). Indeed, the reason I say ‘slow game speed’ instead of just ‘low FPS’ is because the whole visual part of game runs slowly - characters move at a snail’s pace, but I might have something like 24FPS at the time (audio speed appears to be normal). Within a few seconds of clicking out of the Yuzu window, game speed will increase (along with FPS) to a normal level, and even when I click back into the window/set the game to fullscreen, I can continue playing with no game speed issues at all.

I’m not overly concerned as the issue isn’t game-breaking (it’s very easy to fix), but it is odd.

Has anyone else experienced this issue? Does anyone have suggestions about what I could do to stop it happening?

Thanks in advance

Use exclusive fullscreen in config graphics of yuzu. You likely have a gsync or freesync monitor which will have issue here until you use exclusive fullscreen or change app focus

Bingo! Thank you so much Ghost666 - changing to Exclusive Fullscreen and starting the game in fullscreen mode fixed the issue completely. As an added bonus, the whole game started running a lot more smoothly as well.

And yes - you were on the money re me having a G-Sync monitor. I hadn’t even thought of that.

Thanks again - hopefully if anyone else has this issue in future this small thread will help them out :slight_smile:
