Crysis 3 Installed On and Run Directly from RTX 3090 24 GB GDDR6X VRAM
Let's skip ahead of any "Can it run Crysis" introductions for this news piece, and instead state it as it is: Crysis 3 can absolutely run when installed directly on a graphics card's memory subsystem. In this case, an RTX 3090 and its gargantuan 24 GB of GDDR6X memory where the playground for such an experiment. Using the "VRAM Drive" application, distributed in an open-source manner via the GitHub platform, one can allocate part of their GPU's VRAM and use it as if it was just another system drive. After doing so, user Strife212 (as per her Twitter handle) then went on to install Crysis 3 on 15 GB of the allocated VRAM. The rest of the card's 9 GB were then available to actually load in graphical assets for the game, and VRAM consumption (of both the installed game and its running assets) barely crossed the 20 GB total VRAM utilization.
As you might expect, graphics memory is one of the fastest memory subsystems on your PC, being even faster (in pure performance terms) than system RAM. Loading up of game levels and asset streaming from VRAM "disk-sequestered" pools to free VRAM pools was obviously much faster than usual, even more than the speeds achieved by today's NVMe drives. Crysis 3 in this configuration was shown to run by as many as 75 FPS in 4K resolution, with the High preset settings. A proof of concept more than anything - but users with a relatively powerful (or memory-capable) graphics card can perhaps look at this exotic solution as a compromise of sorts, should they not have any fast storage options, and provided the game install size is relatively small.

On a more serious note here - actually, I don't have one. I'll just move along now.
Trouble & strife = Wife.
Definitely worth 1500 :DThat's really all there is to it, I'm still waiting for the eternal 'I installed Doom on my 3090'
that is like saying its odd we all of a sudden do Ray Tracing because that is ages old as well, we just never had the hardware to do it in real time.
Its just that we currently have a capable card with a relatively large amount of Vram, the only thing I find odd is that they did not use the (lacking) Crysis Remaster....wait wait no...probably not enough Vram for it
tl;dr edit: Buy more ram and make a ram disk, it'll be cheaper and faster.
in the third photo you can see how with the aida benchmark the ram of the gpu are slow in the r / w but in the copy being inside the gpu the bus allows it to reach 30 times the speed of the pciexpress 3.0 bus while the cpu still remains in advantage having about 4 times the speed in r / w
