Extremely High Memory Usage with Direct3D 12
0%
Description
With Direct3D 12, the memory usage seems to be significantly higher (about 5x higher) than that of Direct3D 11.
The amount of testing I was able to do with this was very limited, as I only have 4 GB of RAM, and my computer usually becomes unusable when running a game in D3D12, but here's a rough set of values I got:
Lego Star Wars
Direct3D 12 - 1,600 MB
Direct3D 11 - 350 MB
OpenGL - 490 MB
These are rough averages (to 2 significant figures) of the values shown by Task Manager a few seconds after starting Lego Star Wars. Now, if you thought that was bad...
Burnout 2: Point of Impact
Direct3D 12 - 2,500 MB
Direct3D 11 - 350 MB
OpenGL - 490 MB
...yeah. Notice how the values for D3D11 and OGL ended up being about the same as with LSW, but the value for D3D12 is an insane 900 MB higher. I even managed to reach over 2,900 MB, as I said in IRC a couple of days ago.
By the way, I'll have way too much free time on my hands for the next 2 months, so if there is literally anything else that I could do to help, please say. I need stuff to do!

I don't own Burnout/Lego Star Wars so can't test them.

I tested Burnout 2: Point of Impact (NTSC-U, GB4E51) on DX11 and DX12 mode and never saw over ~460MBytes of VRAM usage.
I'm using 2x native resolution, with 8x SSAA.

I forgot to mention this, but I'm talking about DRAM usage, not VRAM usage. I should have stated that in my original post.

Can you see if toggling EFB Copies to RAM or the TExture Cache settings affects it.

Won't be fixed anymore. D3D12 has been removed from master as of https://dolphin-emu.org/download/dev/1880a97bb055b917108b1391d44fa9c04015c289/ and is no longer supported.
