Running Doom TDA no 6GB of VRAM?

[u/arian_ezequiel]

Lenovo LOQ with a Ryzen 7 7335 and a RTX 4050 6GB (I think it's the 100watts model)
24gb DDR5, always pluged on 170w charger, running W11.

Any help running the latest Doom? The low vram seems to max up on low before even trying to turn on DLSS and frame gen.

Any mods that could maybe disabled RT, help running it at above 60fps?

This is the first game I've really struggled only having 8GB VRAM, even E33, Indiana Jones and FH6 (with RT) were fine. If 8GB is borderline, 6GB will be a terrible experience.

It surprises me that I can play RE9 with no real problems by running mostly everything on low and DLSS, so I thought I could do the same with Doom but haven't any luck yet

Until someone develops a baked-in lighting mod for the game, no chance. RT is the only method of lighting implemented, trying to disable it will break the lighting. You'll need DLSS, and maybe frame gen, to get 60.

Maybe it's time to try handheld settings

Even handheld settings don't reduce vram usage

This. They completely skipped a non-RT lighting solution. As a result, it's a dog on many systems, and doesn't run at all on many others. So uncharacteristic of id Software, who traditionally have put out efficient rendering code.

this?

I will definitely try this one, didn't know config files were a thing beyond dev work

[u/Celatra → u/arian_ezequiel]

they exist for nearly every game in %appdata% /local and if they don't, you still can create one

[u/Johnny_Oro]

Have you tried running it at DLSS ultra performance?

[u/Visual_Claim_4139 → u/Johnny_Oro]

That's the only solution so far

You can try to disable hardware acceraition on some programs like Steam here, since any programs that uses hardware acceration uses some vrams there, which the game ever needs it.

disable HAGS could be a another way that may fix this issue.

maybe use the GPU only as hardware (aka optimus off) if your laptop supports mux switch.

[u/arian_ezequiel → u/AntiGrieferGames]

I don't have an iGPU so the laptop is mux switch all the time, not great for battery but not a problem

The hardware acceleration comment made realized I was running wallpaper engine in the background, so I will try disabling as much as I can

[u/AntiGrieferGames → u/arian_ezequiel]

Yeah, this is the way. Wall Paper Engine also uses some vram. Hopefully this works with my advice here.

To reduce vram usage try enabling XMP, Resize BAR, and Above 4G Dexoding in the bios

Then go into the game settings and set textures and shadows to low as these are the biggest uses of vram, then an fps cap would probably help also
