  1. VR Test Discussion

     

    even without the 50% improvement, dcs has not gotten any worse. just fly and enjoy.

    no need getting stressed out about it.

     

    if an improvement happens, it happens. it a bonus, not a blocker.

  2. I could try keeping the settings low and shoot for 90fps but I doubt I would hit that very often with my CPU, not on a busy map

     

    if you can’t hit the target frame rate, there is a bottleneck.

     

    if your case, it sounds like it’s your CPU and adding a faster GPU won’t help.

  3.  

    DCS is CPU or GPU bound for individual users depending on their preferences and the balance of their hardware.

     

    i get what you are saying, but don’t forget, you can take any CPU bound game and force it to be GPU bound with appropriate settings.

     

    when users with 2080TI’s can’t maintain the 90fps the vr headsets are designed for, is the bottleneck CPU or GPU ?

  4. The degree of CPU ‘boundness’ depends a lot on your graphic settings. I can very easily be GPU bound with high SS/PD/shadows settings

     

    sure, you can force the GPU to be the bottleneck if you make it do crazy things.

     

    but it’s always been that way, in almost every game.

     

    when we say DCS is CPU bound in VR, we are assuming reasonable settings on reasonable hardware.

    I'm getting the feeling DCS is still CPU limited, even in VR

     

    yes, it’s CPU bound in VR.

    we’ve been posting about this for a couple of years.

     

    you want a CPU with a fast clockrate, not the most cores.

     

    some users claim this will be fixed with the magic thing called Vulkan, but we will have to wait and see.

  6. And check that DCS.EXE is running on more than 1 core! After the second last update, for me, it now randomly defaults to either running on 1 or all cores

     

    it shouldn’t be random. there is no code in DCS to do this.

     

    do you have process lasso running?

    or any other tools/utilities that “adjust” normal operating system core affinity algorithms?

     

    it sounds like you have something installed in your machine that is causing problems.

  7. Yep, it would be good to get a definitive explanation for this.

     

    Personally, I am very confused by all the posts on these forums that say 'DCS is single core'. followed by endless, 'no it's not', 'yes it is' type responses.

     

    different users test different things with different options in different scenarios.

     

    and some users use different names for different technical details... so yes it can be confusing.

     

    short answer is, all windows programs package work into ‘threads’. some use 3, some use 200+. these threads are then scheduled onto cpu “cores” to execute and do the work.

     

    if most of your program “work” is done in a single thread, then that work can only be done when that thread is assigned to a core (one thread -> one core).

     

    DCS does a LOT of work on 1 thread and a bunch of work on 2 other threads.

     

    in my MP test scenario, those 3 threads gobbled up over 73% of the entire CPU time used by DCS.

     

    ideally, if those threads were always ready to execute, they would run on 3 cores simultaneously.

  8. My understanding is that the number of cores being used is a product of programming

     

    to be pedantic, the programmers have control over the number of threads they use. those threads are then scheduled by the operating system onto cores to execute.

     

    the more “ready” threads and the more free cores, the more things happen in parallel.
