CounterStrike: Source stuttering on MacBook Pro

counter-strike-sourcemacostechnical-issues

My friend is having some problems with CS:S on his MacBook Pro:

if you stand still its like 100+ fps, if you fire there is a millisecond stutter, any fighting and it's completely unplayable

i put cl_showfps 1 and its usually 100odd and green, then it flicks to red (<20fps) for a millisecond

His MacBook Pro is from early 2011 which I believe has dedicated graphics, either way I would have thought such an old game would run okay on his machine?

Thanks

Remember to update both your game and graphics drivers to the latest version to check if this problem has been fixed, first.

There could be many reasons for this problem, namely

Overheating: Microstuttering is a very common symptom of overheating. Does the stutter happen as soon as he starts the game or after playing for sometime? Check the CPU and GPU temperatures before starting the game and after the stuttering starts and check how hot the system is running.

Configuration: Another solution you can try is one linked on the official Steam for MAC forums HERE

Edit or create autoexec.cfg located in users/your username/library/application support/steam/steamapps/your steam account name/counter-strike source/cstrike/cfg to match the following:

//_Set Netcode vars_
cl_cmdrate "66"
cl_interp "0.033" //try "0.0151515" if that is laggy for you.
cl_interp_ratio "1" 
cl_updaterate "66"
rate "25000" // you can try higher, I have mine set to 100000 (probably unnecessary but alwell it is smooth. )
fps_max "60"
