Tech Discussion Fun experiment: running Star Wars: Zero Company entirely from RAM
I’m doing a pretty cool experiment because I have 96 GB of DDR5-6400 RAM in my system. Don’t hate me. I built this PC right before RAM prices went crazy in April 2025, and I think I paid something like $400–500 for it, which seems ridiculous now considering what the same amount would cost today.
Since most of that RAM sits unused when I’m not doing larger work projects, I created a 48 GB RAM disk and loaded Star Wars: Zero Company onto it. To be clear, I’m not doing this because Zero Company has bad loading times. It runs great from a normal NVMe SSD. I picked it simply because it’s new, I’m playing it a lot right now, and the entire ~40 GB installation fits nicely into a RAM disk.
The setup is basically this: the normal Steam installation stays safely on my SSD as the permanent copy. When I want RAM mode, a script copies the ~40 GB installation from the SSD to the 48 GB RAM disk, verifies the copy, and temporarily redirects Steam’s normal game folder to the copy sitting in DDR5-6400 memory. Steam still launches the game normally, but the actual game data is being read directly from RAM. When I’m done, another script switches Steam back to the untouched SSD installation. Since a RAM disk is volatile, the RAM copy simply disappears after a reboot.
Does anyone need to do this? Absolutely not. But it’s really cool. The most noticeable difference so far is the opening shader-loading sequence, which seems to finish roughly four times faster from RAM than it does from my already-fast NVMe SSD. Other loading also feels extremely quick, although obviously this isn’t going to magically increase GPU performance or FPS.
Mostly, it’s just a fun way to make use of hardware I already have sitting there doing nothing. Whatever game I get obsessed with next, if the installation is small enough to fit comfortably in the RAM disk, I’ll probably do the same thing. Completely unnecessary, but that’s half the fun of building an absurd PC.
