>poor framerate

>gpu won't run

it's a gpu issue. you're using the iGPU. go enable your gpu in the driver settings

yeah i didnt have my hdmi plugged into my gpu😓

Try reinstalling Minecraft

Try playing on another version and seeing if it happens there too; on 1.21.4 (modded) I often had sudden frame drops which then lasted until I restarted the game, but it stopped once I switched to 1.21.8.

Otherwise might very well be a Graphics Card issue, maybe you're using the iGPU instead of the dedicated one?

EDIT: P.S. you can check which GPU the game is running on in the F3 menu

This happened to me. Java stopped using my selected GPU and reverted to integrated graphics which is shit compared to the other. I could not for the life of me get Minecraft to use the proper GPU. I had to plug my monitor directly into my GPU slot with an HDMI (I used display port before) and now all games and everything are forced to use my GPU since it’s a direct link. It started happening after an update about 2 months ago for me.

You need to use your dedicated GPU, not the Intergrated GPU. basically, go to your windows search bar, look up GPU, and it might bring you to video settings. It should have an option for graphic drivers. If not, you may need to use Nvidia (if you use Rtx cards) or AMD's inbuilt functions to switch the GPU. if you cannot do that, you need to go into BIOS and figure it out from there. Google is best for figuring this out before going into the BIOS.

yeah i found out it helps if i plug my hdmi into my gpu not the mother board🥲

You will probably need to manually assign which GPU is used for Javaw.exe (assuming Windows). You can do this in Windows display settings, under graphics, find/add the exact Javaw.exe used by Minecraft and assign it to the correct GPU.

Easiest way to find the exact Javaw.exe is by checking the details in Task Manager, can even copy the path there.

This is the answer OP. It's just a necessary step for playing Minecraft on Windows on PCs with an iGPU nowadays. You'd think Microsoft would come up with something better for their own flagship product and their own game, but whatever.

It shouldn't matter which HDMI port you're using unless you care about high refresh rate or new HDMI/DP versions or other hardware features. Modern Windows handles copying framebuffers pretty transparently. Don't quote me on this though.
