Thanks again for the replies.Īnd while on the subject, is anyone aware of a way to set the process afinity so that DCS.exe always uses that afinity? I'm guessing no, as the PID would likely be different each and every time. So, the theory is that the CPU bottle necks and can't feed the GPU any data so the GPU starves for 1-3 seconds depending on how severe it is and you get a prop in rendering. Thank you for that video link as while mine isn't currently happening as frequent as it was in the video, the results look similar exept that my FPS usually drop to near 0 for a second or so when it happens. I'm using 3x 1440 displays but that's pretty demanding as the number of pixels is actually 1.33 x a single 4k display about 11 and Rushx, you know I've monitored the various cores but I can't say that I'm certain none of them are being maxed out. I say Task Manager as MSI after burner tends to give the impression that there is a lot of multitasking going on where as I do not believe that to be the case under only been playing in single player so far, really got into DCS with the release of the F18, so it's only been about three months. Multi player on the other hand adds more variables to the equation. I find with some head room like that drop frames are not usually a problem however I find I get drop frames as soon as GPU hits the wall at 100% :music_whistling:) and the GPU averages around 70%. To improve VR usage I usually dial down the settings so that the CPU sits at around 12 to 14% (aka almost 100% for the one core doing all the bloody work. I have a 5930 6 core i7 4.7Ghz and 1080Ti 1.97Ghz 64GB and SSD etc and still according to Task Manger DCS uses maybe 12 to 14% CPU total usage (but 1 core is at 99.x% usage) seeing that you have a 3GHz clock I'm pretty sure you will have bottle neck on that single core doing most of the work. Perhaps check that one of the cores isn't hitting 100% DCS only uses a few threads if you look at even Task Manager you'll see one real and one virtual core peddling real hard and the others mostly not doing too much. I've attached a screen cap of my last session recorded with MSI Afterburner. I'm just wondering if anyone has any ideas. Running a 5960x 8 core i7 3GHz, I know that's a few years behind now but I'm running DCS on three screens (non SLI surround) at 7680x1440 on three G-Sync ASUS Rog displays and averaging at least 30 FPS. It's not a CPU bottleneck, as CPU usage has never been all the way to 100% for me. This can be very frustrating and have undesirable results when it happens at a critical time like when you're doing a case 1 recovery. When this happens, in sim, everything literally stops for 1-2 seconds and then "catches" up really quick. Other times the game will freeze maybe two dozen times. Some times, I can fly for 40 minutes and have hardly any issues at all. I've tried different drivers, several, different SSD drives, minimizing the software running, reloading Windows and the list goes on. SLI enabled/disabled doesn't change anything related to the problem. I have a 1500 Watt power supply, I'm running 2 Titan X Pascal 12GB cards, only one of which drives DCS as SLI isn't really supported. I can list a whole bunch of things it isn't in my case. I've read possible causes being anything from drivers to power supplies to the moon beams. I'm an IT professional by trade with some 25 years of experience and I can't figure out what the cause of this is. I've been troubleshooting this issue for months without success. If you Google the title of this thread you'll find many posts of others reporting similar issues dating back to 2015 or perhaps beyond.
