    As we all know the RTX 3090 has 24 GB of video memory. For most games today, that's an abundance of vram even on the toughest settings. Twitterer 'Strife212' has found a creative way to make use o...

    Crysis 3 runs from video memory of an RTX 3090 24GB

    Interesting what she did, but just only interesting. I see no advantage on doing that, because it will use the same pcie lanes for the storage and for the video memory. I would like to see how it runs with a standard setup, I bet it will be faster or equal. Anyway... it is a kind of test I also like to do :D

    Thankfully PCIe4.0 has plenty of bandwidth! :rolleyes:

    Very Very nice, Not surprised either, just matter of time for someone to try something like this.

    Excellent, thanks for sharing.

    Because of how information is supposed to be loaded into VRAM, yes, the PCIe lanes would be a major bottleneck. However, it would still be faster than loading data from a the average NVMe SSD, because you'd get all x16 lanes to transfer data instead of the x4 that a SSD is limited to. Though technically, you'd have x8 lanes to deal with since for asset data, you're basically passing information from the VRAM to your system memory, which is then put back into VRAM.

    If the software (or perhaps even drivers) were written so game asset data wouldn't have to be passed back and forth like that, then there wouldn't really be any PCIe bottleneck at all; the rest of the CPU-side code would load in a second.

    lol brings a whole new meaning to but can it run Crysis?

    Yes but too much IO...
    The maker of the software she used quote that it is still slower than regular ramdrive due to that.

    Anyway it has to be done, not just to check if it is possible, but also because it's fun :) (Well done strife212 :) )

    Remember TechTV before it was G4? They installed and ran Quake 3 on system memory, I think it was 1 gig.

    I believe that data has still to go back to CPU and being re-read there.
    I would imagine a decrease in performance all in all using this method.

    She is using a 9900K so only PCIe 3.0. So plenty of way to improve performance if grabs a Zen 2/3 on X570/B550 :D

    Saying that, is a damn great achievement. :D
    Still remembering the day my mate said "why you bought 120MB drive? 20MB more than enough". hahah
    How far we came in 30 years

    I think Linus ran crysis on amd 3990x threadripper alone with no gpu

    I find the weird stuff people run Doom on to be more amusing. This is kind of interesting, in that same respect.

    Guessing she would be sabotaged by software, because the OS and game will still try to store the most used things on system memory, because 99% of the time, system mem is faster then SSD drives.
    I do not think the OS runs speed tests to see if the game install drive is faster then system memory.

    Was thinking that. System ramdrive would probably give much better results... but still, what an interesting thing to do!

    Has Doom ever been, or could it ever possibly be, installed on the cache of a CPU?

    What's the difference between this and running Crysis or any game or app from a RAM DRIVE? ARMA players have been doing this for a while before SSDs and I think even old Amiga, Atari ST or Mac users did it before too...

    Its a RAMdrive, this guy did nothing new.
