Limit CPU load

Hi@all,

ich spiele 0ad auf einer mobilen Workstation von HP

When I start 0AD the game uses 100% of the CPU. Therefore the fan runs all the time and the notebook gets warm accordingly.

i have tried to limit the process (0ad) with the help of cpulimit but it does not work

me@lt001:/usr/games$ cpulimit --pid 4342 -c 1 -l 1
Process 4342 detected

is there a way to limit the CPU load when starting 0AD?

Hello,
in game options you can try to limit fps, settings -> graphics, it should help with cpu load.
Aside from this, game is more-less single thread bound so all simulation computations occupies your 1 thread.
If you start game first time, load can be higher, but later it should not be so much.
Does it run always at 100 % ?
Also to my knowledge modern cpus are fine with running at 100%, but maybe you could check the graphic settings if fans are too loud,

ok, I set all graphics options to the lowest value. CPU load is now at 50%. The fan is still running continuously :-(

btw some computers can setup  modes, e.g I can have 3 settings, in highest one graphics tries to render max quality and cpu works really hard so fans will run like crazy. 

But I never use that one

 

if you do not have that option in your pc, there are always some settings in windows (additional power settings), which can influence how hot your laptop gets. Basicly you can limit there maximum speed/work for your cpu and other things.

Try running 0 ad in windowed mode.
