Why there is nvlddmkm path for you? Did you have a Nvidia gpu? Afaik it is for Nvidia gpus. As you are using RX580, if you had a Nvidia gpu, you had to use DDU to clean the nvidia stuffs.
i did use ddu and i never had nvida, i will delete the nvlddmkm key.SeekNDstroy wrote: ↑16 Jan 2025, 10:07Why there is nvlddmkm path for you? Did you have a Nvidia gpu? Afaik it is for Nvidia gpus. As you are using RX580, if you had a Nvidia gpu, you had to use DDU to clean the nvidia stuffs.
explain the tweak or give link ?agendarsky wrote: ↑16 Jan 2025, 13:33guys please do the usb 2.0 controller mode trick. No regedit tweaks will help until you fix root of the isue which is either bad usb driver or game engines cant handle such speeds without being incosistent.
you have nvidia right,if some one give the amd key i can make benchmakrs, before and after, i think for is this the key but i am not sure?Jonnyc55 wrote: ↑21 Mar 2025, 10:50"DMA remapping isn't supported for graphics device drivers."

Valid values for DmaRemappingCompatible:
Value Meaning
0 Opt-out. Indicates that your driver is incompatible with DMA remapping.
1 Opt-in. Indicates that your driver is fully compatible with DMA remapping.
2 Opt-in, but only when one or more of the following conditions are met: A. The device is an external device (for example, Thunderbolt); B. DMA verification is enabled in Driver Verifier
3 Opt-in
Say not supported for gpu driver yet my default is 3

ok so if someone knows,maybe give source and maybe then benchamarks?Jonnyc55 wrote: ↑05 Jun 2025, 11:38Sorry yes Nvidia, 3060.JimCarry wrote: ↑21 Mar 2025, 13:27you have nvidia right,if some one give the amd key i can make benchmakrs, before and after, i think for is this the key but i am not sure?Jonnyc55 wrote: ↑21 Mar 2025, 10:50"DMA remapping isn't supported for graphics device drivers."

In the link I provided in other post, I wasn't clear, it says in a warning box:
"DMA remapping isn't supported for graphics device drivers."
Yet we see this key for the GPU. I can only think, windows OS merely sees a PCI device, and adds the key anyway. However, there's no telling how Nvidia GPU will work with the registry key, maybe does something with it by itself. So mine was default 3, and I set it 0.
Well if it helps mine was in:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm\Parameters, but yes. amdwddmg, no idea if that is the target for you.
