GpuRamDrive VS vramfs

While it is not a 1:1 comparison there has been a driver for windows that allows the creation of a ram drive from vram for NVIDIA cards.

Yes it is possible. Here is a GitHub project that allows you to create a virtual disk using VRAM. And here is where someone installed Crysis 3 into VRAM on a 3090

Its probably the GPU VRAM. Unfortunately most of the 'tools' that I seem to be finding to test that are the equivalent of '10 easy steps for a faster PC, your never going to beleave #7... 1) give us money!'. But memory is memory, and to that end: https://github.com/prsyahmi/GpuRamDrive. Get that, something like MSI afterburner that can read VRAM usage. And your going to need some more cat videos... Set up the RAM drive, you probably want to leave about 2GB free for the cat videos to run, then load up the new drive with the cat videos (you can get one and just rename it a bunch of times) if you can get 4 or so running at once, that should fill up the last little bit of VRAM. Hopefully at some point something will crash or glitch. If it dose, reset everything and make sure that the cat video itself runs.

I downloaded the gpuramdisk project from https://github.com/prsyahmi/GpuRamDrive and added my own gpu virtual array into its memory manager for a multi-gpu support on single ramdisk.

For anyone looking for the answer: Here is the link to it. https://github.com/prsyahmi/GpuRamDrive/releases It's actually a lot slower than a normal RAM disk, by over half the mb/s, which really suprised me. However, it might actually still load faster in games but I haven't tested that yet. That being said, it does actually increase your performance a bit, not by a whole lot, but it can be noticable regardless

You could use it as swap space via vramfs, but again, if you hit the swap, you already have lost.

This reminds me of vramfs and swap on video RAM. The tweet also has some interesting insights specific to Linux, which may actually be more viable now that PCIe ReBAR is more widely supported, allowing the CPU to actually access all of the available VRAM instead of a limited window of about 256 MiB.

Serious question, I've had similar thoughts but with swap on a GPU-backed filesystem
