Avatar World game stutters on my Dell desktop, runs fine on other PC

I’m currently using a Dell desktop ( Inspiron 3910 ) running on Windows 11 with integrated Intel graphics.

When I dive into the Avatar World game on this PC, the frame rate drops significantly, making the gameplay feel really choppy. Interestingly, I have another non-Dell PC with similar specs, and the game runs just fine on that one. So, I’m starting to think the problem might be tied to this Dell machine.

Here’s what I’ve already tried:
– Updating Windows to the latest version
– Installing the most recent graphics drivers from Dell Support
– Lowering the in-game resolution and adjusting the graphics settings
– Closing all background applications and switching to the High Performance power plan

Are there any specific graphics, BIOS, or power settings for Dell that I should tweak to boost performance in games like this? I’d really appreciate any tips you might have.

Thanks a lot!
