Windows is -not- an realtime OS... you will never get a deterministic behavior to the way you want it. ACPI's default time quantum is crap, TSC is better but it doesn't work for SMP. So you have to decide which is better, ACPI with SMP and 512fps maximum, or TSC-like with single processor support and 1000fps maximum.
Valve can't fix it because it's not broken (it's an OS/hardware issue with ACPI, alfred can tell you more about it) MS is generally terrible for their time quantum's and other things. At 08:01 AM 2/15/2006, Ilya Oboznyy wrote:
-- [ Picked text/plain from multipart/alternative ] 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...
