Yeah, actually, trying to run something fancy on top of legacy PC in Linux is just a fun game by itself
So this is definitely not a general game recommendation thread. Would be nice to see what relatively modern title people had managed to play on aged hardware.
I have Core i5 ULV 2.5Ghz/Intel HD Graphics 4000/Linux. I play
Clone Hero on it in 1080p with all effects enabled. It is Unity, but surprisingly not very demanding. When turning on video or animated backgrounds, had to downscale to 720p, cause framerate sometimes drops.
On this mobile chips you should set CPU frequency ‘performance’ governor via
linux-cpupower and put Energy Performance Bias to maximum during gameplay to have reserved overclocking unlocked. In order this to work, make sure there are no conservative “powersaving” features turned on somewhere in BIOS. There also
gamemode-tools available for this, but I found executing simple script is more reliable.
And one more thing, I have discovered that a good power source is a must. If your charger is pretty old or broken or you have low voltage in your socket or disruptions in electricity supply, the laptop might automatically switch to energy saving throttling hardware mode (like when there is low battery level), and only turning off and on could bring it back to max speed.
As well, additional cooling is not only for high end systems. These oldies throttle down to snail’s speed when overheated. Not much of a problem in winter, just consider it as generic advise.
