HELP: High CPU Usage when play Diablo 2

i tried all of these solutions, but it still seem no hope

Does it happen on single player also or only on multi? Try running the game without D2SE. Most likely the solution is to install and use glide and set a FPS limit <100 or force an fps limit from your gpu driver if you know how to do that (requires nvinspector for nvidia cards).

I tried both SP and Multi, tried with D2SE and without D2SE too, my glide is set at 30 FPS limit. I'm finding some software that can limit CPU Usage for Diablo 2

Thank you guys anw for helping me

You've tried even the dll solution and still didn't work?
I totally feel you, I was where you are, was searching for days for a solution and just when I said I give up, I fixed it

Is the High Cpu incident occur when playing normal Diablo 2 also?
If you open Median on window mode and you click out of the game (so the game is like in a minimized state) is Cpu still that high or is it dropping down?
My advice, is to try fixing your problem out of D2SE first (I mean with normal launcher).
Don't forget to check the Override DPI scaling box and try all three options. From my experience this thing is TOTALLY messing almost everything on Windows 10.
Waiting for your feedback. I hope we can make it work!

Dumb suggestion possibly but I had a problem like this and restarting my computer actually helped.

I think i have to reinstall my windows, but now i have so many softs and files that relate to my work.
So sadddddd

Ok Max. let's try again.
Change your Power settings to High Performance.
Change performance settings from MY COMPUTER'S properties and advanced system settings to favor performance instead of appearance.
Disable Themes service.
Change your graphic cards settings to favor performance.
Try to monitor what's going with your CPU with Task manager's Resource Monitor (have Diablo II opened in windowed mode and have Resource monitor next to it and keep track of what's going on.
You can try to monitor more stuff with Process Explorer program too I think.
Waiting for feedback. Good luck!

Never heard of Win10 causing this. This absolutely sounds like your computer isn't using your dedicated GPU and is defaulting back to the integrated chip. Double check that. I'd suggest also installing software that can display your GPU temperature and fan speed in real time. When you load up a video game GPU temp should start rising due to load, with a commensurate rise in fan speed. If it doesn't do anything, it 100% isn't using your GPU.

I had to set D2SE to use the Nvidia GPU (not d2). I expect that's what you meant but it seems worth mentioning just in case it helps.
