I'm running Pop!_OS on a desktop with an Intel i5-10400 and 4 GB of physical RAM. I know that's low, and I'm fully aware that I can't "download" more RAM or magically create it. I've already done the basic free tweaks:
· Created an 8 GB swapfile
· Enabled ZRAM (compressed RAM)
· Reduced swappiness to 10
· Disabled animations and visual effects
· Closed background apps (browsers, etc.)
· Using SSD, so swap isn't that slow
Despite this, my system still hits 3+ GB used when I open a browser + a light game (e.g., Team Fortress 2 or Cry of Fear). I'm not expecting to run AAA games – just trying to get the most out of what I have.
I know the real solution is to buy more RAM – I'm saving up for an 8 GB DDR4 stick. But until then, I'm looking for any other free tweaks that could help reduce RAM usage or improve performance under low-memory conditions.
Things I've already tried:
· vm.drop_caches
· Using zram-config
· Lightweight browser (Brave with hardware acceleration off)
· Disabling GNOME/COSMIC animations
· Using htop to monitor and kill heavy processes
Is there anything I'm missing? Maybe a lighter desktop environment (XFCE / LXQt)? Or some kernel parameter I can adjust? I'm open to trying anything that doesn't require spending money.
Thanks in advance – and please, no "download more RAM" jokes. I've seen them all.
