Can't play Doom 3, FPS is SUPER slow

Hi y'all. I am trying to play Doom 3 off of Steam on my laptop. However, the framerate for some reason is SUPER slow. I am not talking about even the in-game framerate. Like the framerate in the menu and even the opening cinematic showing the id company logo is extremely slow. Is there some sort of fix for this? I have been playing through Doom 3 BFG edition but I want to play through the original to get the absolute original experience. Any help would be really appreciated.

Laptop specs if applicable:

ASUS

Windows 10 Home

Intel Core i7

Nvidia GeForce GTX 970M

I see you're runing a laptop, maybe the .exe from Doom 3 on Steam run on integrated graphics card and not on the onboard graphics cards (GTX 970M), so maybe check that out.

And i would recommend a Source Port from Doom 3 to tweak and maybe make it run better that the Original version.

Yes, Doom 3 in 2024 will run at full speed on any Intel integrated graphics from the last 5 or so years.

Have you also tried comparing how it runs when your laptop is on the charger as opposed to running off battery? I know for some of my games, I need to change the power settings in Windows and my graphics card to run games smoothly on and off the charger

I got it to work using Dhewm 3 source port. Appreciate everyone's help.
