TF2 - huge FPS drops

Look at this:

I've done this:

What is your CPU usage on a full server?

if you would have done this completely you would not have fps_max 300... please try everything, especially what is written in the trouble shooting and playing arount sections.

When i running old kernel, empty TF2 server usage 50% CPU . After kernel optimization empty server usage only 4% CPU. With 24 players on serwer CPU usage is about 90% but even with 16 players, FPS drops to 80. It looks like the Intel Core 2 E8400 is too week or broken or something. I've tried to do everything.

cpu usage isn't useful for game servers, the kernel cannot measure it correctly for processes that behave like game servers... simply ignore it and look at the fps stability.

most certainly not. I had a E8200 for quite some time, it hosted 4 servers at a very high quality, one tf2 among them.

unlikely. a broken cpu would simply crash your root server.

i don't believe you

especially you did not react on my last post.

i've done it completely, i've run server with max_fps 1000 then i switch to 300.Theres no Diffrence between 1000 and 300 , more than 14 players on serwer = ~80 FPS and tickrate constantly drops to 17 (CPU usage 70-100%)

I don't think i can give you much help because i never had this kind of problems, but :

Do you have KAC installed (If you don't know what this is then you don't have it)?

I don't think so....


BTW Now you can see 2 posts above - 20 players = 20 FPS max / CPU usage - all time 100% and memory 20%

Can you please give us your plugins list?

sm plugins list.

did you try everything in the trouble shooting section? are your priorities correctly set (if yes try without setting them)? was it better before changing the kernel?

No diffrence , on both kernels - 20 players on serwer = 20 FPS max and cpu usage 100% all time

Problem solved - i've simply changed C2D E8400 for Quad Q9550. 28 players, 1000 fps max with no drops , 60% CPU usage. Looks like CPU was the only problem. Thx for help.

really strange. maybe the cpu was misconfigured and did not run with full speed. I had a better performance on a slower cpu.

Maybe yes, but i dont have more time and ideas to check it
