Someone has installed ‘Crysis 3’ on an NVIDIA GeForce RTX 3090: it works and also in 4K resolution

At the beginning of September NVIDIA introduced its GeForce RTX 3090 graphics card, a real beast with 24 GB DDR6X of graphics memory. A GPU that’s certainly great for playing video games without graphics performance issues. But what if the video game is installed directly on the GPU? This is not the way things are supposed to work, but never underestimate the ingenuity of a software engineer .

As @ Strife212 has indicated on Twitter , the madness of running ‘Crysis 3’ on a GPU is viable . The idea of ​​video games and applications in general is to install them on the hard drive or SSD and use the GPU to improve the graphics. In addition to the RAM for the processes carried out by the computer’s CPU. But it is not a universal rule and 24 GB of memory that the NVIDIA GeForce RTX 3090 brings integrated go a long way.

A video game in the virtual memory of a GPU, and without apparent problems

The 24 GB of the NVIDIA GeForce RTX 3090 is virtual RAM . This helps the GPU to process data better and be more powerful. VRAM, like RAM, is not an ideal place to install anything because it is random and volatile memory, from which everything is erased at the end of the process or if it loses power. While it may be faster than an SSD, it just isn’t what it was designed for. But here we have come to play.

Explains @ Strife212 that he created a 15GB NTFS partition on the VRAM of his graphics card with the help of an app called GPU Ram Drive. With that, essentially, you had a hard drive inside your GPU. From there it was a matter of installing ‘Crysis 3’ and playing.The 15GB NTFS partition from the GPU, which appears as just another partition in Windows. Via @ Strife212

And the result? According to @ Strife212 he was able to run ‘Crysis 3’ without any problem on his GPU . In fact, when playing, he set the game to 4K resolution and with the graphics at maximum. In this state the total memory consumption (between game storage and pseudo-RAM) was about 20 GB. The NVIDIA GeForce RTX 3090 still had about 4GB to spare. The GPU was actually working at only 40% capacity.NVIDIA GPU performance with ‘Crysis 3’ running. Via @ Strife212.

‘Crysis 3’ has often been used as a benchmark in terms of computer power and GPUs in particular for moving quality graphics. The game is from 2013 and the technology has evolved a lot since then, although little by little it is becoming a meme because of how people use it to run it on all kinds of devices.

Usefulness of this? Not much beyond curiosity. The surprising thing about all this is that no one has run ‘Doom’ on the NVIDIA GPU yet .
