Why are you sure you need 1000fps? Are there actual, quantifiable
performance increases (eg, lower ping), or is it all a matter of how it
"feels"?

im speaking about HLDS and im sure that i need 1000fps

512fps is fine for SRCDS because you only have to have enough I/O to
support
the tickrate for the amount of players you have. (Does that make
sense?)
For HLDS FPS = I/O = Tickrate so the higher the better to reduce
calculation latency, which is unavoidable in SRCDS.

I am looking for patch wich will change it to (1000 / 1ms =
1000fps) or get
a specific ACPI driver, like ACPI PC but for SMP, or just ACPI
multiprocessor with 1000fps... I think Intel or Microsoft or Valve
can help
with solving this bug, or advanced programmer... Maybe its possible
to get some DLL from ACPI PC wich changing timer and put them to
Multiprocessor driver... Yes i want 1000fps on Windows and with
normal performance of both
CPU's...

sleep() returns about 1.95 on windows.. (1000 / 1.95ms = 512fps)
usleep() on *NIX returns closer to 1 depending on the OS.
It's a bug in HAL i believe on windows. If you don't use ACPI, it
doesn't use ACPI as a timer anymore and uses TSC..
Only way to get super high frames is to a.) not use ACPI anymore
which disables SMP on windows (i'm guessing) or b.) use *NIX

Hello!
Firstly i will start with my hardware and software:
CPU: Dual Xeon 3200 FU
Motherboard: Intel SE7520JR2ATAD2
OS: Windows XP pro SP2 (Also tried Windows 2003 server, x64
editions of XP/2003, even tried beta version of Vista/longhorn)
but the problem is still the same. (something about NT core?)
Program: HLDS ( Half Life Dedicated Server (using sys_ticrate
10000 (limit number of updates))).
Drivers: I am using all latest drivers, system updates and
firmware.
First of all i dont really know how to explain it technicaly, the
thing i will talk about is called Windows Multimedia timer /
system timer / sleep time. I am not sure about correct name, but
you will understand it from my future words, at least i hope so.
By default this timer is running on Windows systems with 16ms
delay, when im running my HLDS i am getting 64updates per second,
and it addes around 16ms in ping, i noticed that if i start media
player with paused movie in same time, i will get 512updates and
around 3ms delay. That means that Windows Media player making
this timer lower. But its only 512updates, while limit of HLDS is
1000. I was looking for a solution for a long time and finally
found! I changed ACPI driver to ACPI PC and yes! I got 100fps by
default (~5ms delay) and 1000fps and zero delay with Media Player
on! It was working perfect on my home PC with only 1 CPU. On my
server with Dual Xeon it was working also but... But it seems
that only 1 CPU was working, ACPI PC isnt that good for
Multiprossesor system, i lost a lot of hardware power with it, so
i changed it bacl to ACPI multiprocessor and having only
512updates
on
my
server atm.
The question about my problem is:
How can i get 5ms delay or 0 delay with media player on, without
losing any hardware resources(With normal ACPI multiprocessor
driver). I remember it was good in old windows 9x times. (Maybe
its possible to change timer over regedit or over some services
or get some specific driver).
- on Linux systems this problem can be solved by changing kernel
ticrate to 1000HZ.
I hope to hear a solution for getting zero delay on Windows
system. Thank you!
