Server FPS Problems

[hip]

I have a wierd problem with my fps on the server when running on linux. I already did all kernel config updates(1000hz,etc) already.

When I set the max_fps to 100 the "rcon stats" shows consistent 97
When I set the max_fps to 333 the "rcon stats" shows consistent 329
When I set the max_fps to 500 the "rcon stats" shows consistent 494
When I set the max_fps to 1000 the "rcon stats" shows consistent 987

Some of you may say, why doesn't this numb nut set his fps at 600 to get 500? When I do that I still get 494, when I set it to any value between 500-800 I get 494 and anyvalue above 1000 still gives me 887.

Any ideas?

I've tried 3 different kernels, one was stuck at 333fps, the other does the same as now.

Thanks

These are generally the values you will find your FPS set. Theres seems to be "set" values for these no matter what you put.

Normally being ~64, ~100, ~333, ~500 and ~1000.

Do you know why I can't reach the exact "set" value? If I can get 987+ fps should I able to get a perfect 500?

Its just nigh impossible really. With all the goings-on and shenanigans that happen on a server (a player fires a deagle, bomb explodes, physic calculations etc) - theres too many variables (bandwidth, unexpected CPU spike/stutter, number of players connected, tickrate etc) for the server to run a constant 500FPS or any FPS.

Theres been a discussion about something like this going on for a while now over at the hlds_linux mailing list:

Aptly named, "The 1000FPS Fairy Tale"

consistency is better than high fps, shoot for the highest number that the server can reach consistently.

Thanks for the replies,

I messed around with settings, Low Latency Desktop, High Resolution Time Support, Tickless Off, 1000Hz/UserHz

Seems good, I'll mess around with a few stuff and I'll update you guys if I do ever reach the "magical 1000"
