NVIDIA GeForce RTX3090 comes with 24GB of VRAM. That’s a lot of video memory, right? In fact, PC gamers can even install entire games on it and run them. Yeap, you read that right. Software Engineer “Strife, la fillette révolutionnaire” has installed and played Crysis 3 on the VRAM of the NVIDIA GeForce RTX 3090.
Strife212 has used GPU Ram Drive, a VRAMdrive software, and made a 15GB NTFS partition on the GPU. Then, she installed Crysis 3 on it which apparently worked fine.
I installed Crysis 3 on my graphics card!

In 4K/Very High settings, Crysis 3 ran with 75fps on the NVIDIA GeForce RTX 3090. Furthermore, and with the game installed on it, the total VRAM usage was 20GB.
Now in case you’re wondering, the loading speeds did not improve. As Strife212 said, loading times similar to those of a fast NVMe drive.
My guess is that the game needs to transfer the data from the VRAM to the RAM, and then feed them to the CPU. Since Crysis 3 was not develop to take full advantage of high-speed transfers, there is no big advantage here. Of course this could change once DirectStorage becomes available. However, and by the time games start using DirectStorage, they will be too big to fit on RTX3090’s VRAM.
Still, it was a really cool experiment so kudos to Strife 212!
