Nvidia vram leaks probably won't respect this either
So, is this virtual VRAM stored on the other memory chip we don't have supply for?
Unfortunately, not all applications actually set priorities via VK_EXT_pageable_device_local_memory. As for native Vulkan applications, I haven’t observed any idTech game using the extension directly, at least :/
The D3D side looks a lot better, because vkd3d-proton already uses VK_EXT_pageable_device_local_memory when available, and translates both the ID3D12Device::MakeResident/ID3D12Device::Evict API calls as well as priorities set via ID3D12Device1::SetResidencyPriority to priority values set using the Vulkan vkSetDeviceMemoryPriority command. Lots of D3D12 games utilize at least one of these APIs, so the hints these games provide will now be utilized.
My experience with Linux gaming is that Proton tends to work better than native applications, even when both are available, and it seems this might extend the trend.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
