I recently hooked up my Acer Nitro V15 laptop (which has an RTX GPU) to a Lenovo G34-30 ultrawide monitor using DisplayPort. The monitor supports a resolution of 3440x1440 and a refresh rate of 165Hz. I verified that the refresh rate is set correctly in both Windows and the NVIDIA Control Panel. However, I'm facing an unusual issue: my frames per second (FPS) in games is capped at roughly 345. Before I made this switch, I was easily reaching over 1000 FPS with the same game settings on my old monitor.
I've already turned off V-Sync, FreeSync, and G-Sync in an attempt to remedy the situation. The NVIDIA Control Panel shows no FPS limiter, and my power settings are configured to 'Prefer Maximum Performance.' My laptop is set to use only the external monitor, so the internal display is not affecting anything. I also confirmed that there are no background applications like RTSS or OBS running.
I'm using NVIDIA super resolution, but I'm not sure if that affects anything. Specifically, I'm experiencing this in Minecraft with the Feather Launcher, and my FPS stays capped at 345 even when adjusting chunk settings. Interestingly, when I lower the monitor's resolution, my FPS spikes up to around 700. Any advice would be greatly appreciated!

The FPS cap does seem odd, especially since you've ruled out a lot of potential culprits like V-Sync and software interference. Have you checked to see if any settings in the NVIDIA Control Panel might be limiting performance? Sometimes, specific settings can inadvertently cap your FPS, even if everything else looks good.
I totally relate to your struggle! It sounds like the increase in resolution could be playing a big role in reducing your FPS. Even if the laptop display is off, your GPU might still be working harder to manage the higher resolution. I'd suggest checking your GPU and CPU usage while gaming to see if they're maxed out. It might also help to tweak some graphics settings in Minecraft to see if that boosts your FPS without switching back to a lower resolution.
Yeah, that makes sense! And since you’re running on an ultrawide, maybe trying to adjust some visual effects or reducing the render distance might help get those FPS numbers up without changing resolutions.
I'll double-check the NVIDIA settings again! I occasionally overlook some of those small tweaks that can make a difference. Thanks for the suggestion!
