Valve Engineer Drops VRAM Hack That Supercharges Linux Gaming on 8GB GPUs - briefly
(hx) 02:03 PM CEST - Apr,12 2026 - Post a comment / read (4)
A Valve engineer has stunned the Linux community with a clever VRAM management hack that prioritizes GPU memory for foreground games, pushing background processes to system RAM when VRAM fills up. The solution, built with kernel patches and tools like dmemcg-booster and plasma-foreground-booster, delivers noticeably smoother gameplay in demanding titles such as Cyberpunk 2077 on AMD GPUs with 8GB or less VRAM. Early adopters are already seeing strong results, with quick integration into distros like CatchyOS. Patches are now headed for mainline kernel inclusion to make the fix widely available. This breakthrough could significantly improve Linux gaming performance for budget hardware users.
Vock tested Cyberpunk 2077 with an 8GB GPU and saw 1.37GB of memory spilling into the GTT, which stands for Graphics Translation Table and is responsible for telling the GPU to look for something in system RAM. The game was only consuming around 6GB of VRAM; despite having an 8GB pool, it could have maximized instead. Vock's fixes specifically target this via new patches proposed to the Linux kernel.

Their cards, drivers are shit and it’s open source, so that sums it up. I can imagine the security breaches and hacks. Watch this space, coming soon….
Nothing to do with Windows, but how crap AMD are in optimising - or not.

I’m running Cyberpunk punk 1440 max at around 100fps smooth as silk with an RTX 4060 8gb. Never had one crash either.

Shitty AMD technicians, more like
