Why can't TPT run faster?

  • byzod     20th Apr 2013 Member 0 Permalink

    With 120k+ pixels on screen the fps drops to 8-10fps while the CPU usage is only ~ 13% (4 cores) on my machine.

    Can TPT use more cpu resource (or GPU resource in the future) to improve the performance?

    There have been modifications that allow use of all cores but AFAIK it becomes unstable when multiple cores are used.

    13% of 4 cores meaning 50% of one core? I have no idea why that would happen. It should use 100% of one core unless it's hitting the FPS cap (60fps). 120k+ particles of what?

     

    Making TPT able to use multiple cores would be nice, but is rather difficult.

     The cores could be hyperthreaded. In which case it would only use maximum of one thread, which still would be using most resources of that core so it doesn't matter that much.

    There has been multithreading attempts but it becomes unstable and sometimes slower?..

    tpt.setfpscap(99^99)

    That is Uberness....
