Baisse des perf de CSS

Messagepar janpepu » Dim 03 Juil, 2011 22:14

Hi all -

Free to Play brought a huge influx of new users to Team Fortress. To help server counts scale up to match the demand, we are reworking the dedicated server for performance. We want to improve player responsiveness as well as to reduce CPU usage so that hosts can run more servers per physical server.

Some of those changes addressing CPU usage went out last night. Server operators should see a big decrease in CPU load and can potentially run more instances per physical box now. However, a side effect that many of you have noticed is that server FPS has an effective cap of 500 instead of the previous 1000, or possibly even lower than 500 depending on your Linux kernel HZ setting. This should not have a noticeable impact on gameplay as the tick rate is still locked (well, mostly locked) at 66 updates per second and the frames that are being dropped are "empty" frames that do not actually run a server tick.

We're going to address this further in another set of performance improvements. Sorry for the temporary confusion, but we wanted to get these CPU load reduction changes out quickly to help with the Free to Play user crush.

Longer term, we want to move away from FPS as a measure of performance and instead show actual load and responsiveness (jitter/latency) statistics. The difference between a tick and a frame is complicated, and fps_max sometimes affects performance in counter-intuitive ways. We would like to retire fps_max for servers and replace it with a more obvious server performance setting. We'll give you all a heads up before we do so.

Hi all, a heads up to TF2 and CS:S server operators -

A near-future update (not necessarily the next one) will change the way that
framerate is handled in the dedicated server. All users, especially those with
very low pings, should receive a smoother gameplay experience with less jitter
and more consistent-feeling latency.

Another effect of these changes is that all Orange Box (TF2, CS:S, etc)
dedicated servers will run with a locked framerate, similar to L4D/L4D2. The
fps_max convar will not have any effect on servers. (It remains as a client
option since limiting your FPS can reduce GPU heat and overall power
consumption.)

Although we don't normally give notice before updates, this is a potentially
disruptive change for the server rental market, so those who currently charge
premiums for "higher framerates" should probably start considering their
options now.

Fini la course aux performances coté serveur, apres la maj de merde avec orange box, on va vers les 60 fps.

Ce jour le dedié repassera avec un kernel stock à 250 hz donc.

Il vaut mieux se taire et passer pour un con plutôt que de l'ouvrir et de ne laisser aucun doute à ce sujet.
