Today i see some really weird effect on my server (14ppl playing):
I go spectator and flying around with net_stats and thought "wtf, always over 100 fps", then i thought: "why is my graphics card louder than normal in ns2?"
I mean, i had over 100fps outside the map, were i can see MUCH more than in 1st person view.
If i fly to an fight with 6 ppl, it drops to 70 fps.
In 1st person view i get around 60 with spikes up and down. Can go to 30-40 in closefight.
My System is an 2500k@4,3ghz and a 5870@default
Small analysis:
Outside map - Graphic card load at 65%
1st Person - about 45%
CPU use is about 20% more in specmode too.
So, small question to the devs:
Is this a bug? (for me, it seems like that)
Can we get that "turbo" in 1st person too?

From this example it becomes quite obvious it's not the graphics (or settings), but indeed the game code and physics, also this is a known issue :)
I don't really see a difference when using r_gui true/false though. Perhaps a ~1FPS change, I guess...
Space gives you a snapshot. [ and ] move left and right in the snapshots.

Im sure ure right, cause im not a programmer, but:
In your example the client has much more to do, wich ends in higher cpu and gpu load. So, why we have more cpu and gpu load without that collission stuff.
Maybe it isnt very effective, hmm. But that mean, its a huge slowdown for the engine, cause over 100fps ingame are possible.
Havent tested on my system yet, but i also get a major FPS drop when going from spectating to spawing. Like from 70 to 40ish.
In many other games the HUDs can have a major impact on the FPS. I would also guess that you would get higher FPS as alien than marine since the HUD for aliens is so much simpler.
Ill jump in again and use the r_gui command and check.
My System Phenom X4 955 , HD5850.

In other builds i have avg 60 fps but now i have avg 30 fps...
the fps now are more solid only go down when tick rate is low.
lowering the resolution from 1080p to 720p and got the same fps.
the only way to get more fps is overclocking the cpu.
spectator 60 fps
Edit: Make that 3-4 fps. Nothing much. Thats on an empty server though.
people were suspecting already on first day that the hud could be the source of an fps issue: it's not. i disabled it entirely (also the whole gui animation system) to compare and there was not a single fps difference.
In RR I can get around 140FPS and in Xroads it still drops from very well to very bad.
Also it feels like each ent cuts 0.5FPS. Also like Swalk mentioned if I am waiting to spawn at the IP i get around (after the 1. Death) 75FPS, and as soon as I spawn it drops to something like 55.
Changing atmospheric to false didn't, just a guess because of mentioned above, affect my FPS. But in this build a bad Tickrate damages the game more than in build 187 and also high pingers are horror. Around 15 Ticks explode animations stop playing.
A thing that is strange to me is, that after playing some rounds of MW3 (on PS3) Playing Skulk feels like playing in slomotion. The Marines seem to be faster than the "mobile" Aliens. Maybe it is because of the FOV difference but it feels weird and I will never play both games on 1 day again.
Ah anyone also gets some barcode looking shadows? For example the rockwall shadows in the RR of summit.
But you are right nonetheless in stating the NS2-skulk is slow, it is. Painfully.
Also NS2 does some weird stuff with 4:3 vs 16:9/16:10 apparently, where other games tend to show more on the sides when using a wide screen format, NS2 crops the 4:3 to widescreen. So on widescreen you actually see less (top and bottom are cropped). Found that out while testing a few different resolutions to see if I could make NS2 crash (which it didn't :P )
