Hello. I noticed that the default msfs aircraft seem to have a stutter linked to the avionics/displays. When idle in cold and dark I can see constant small spiking in the coherent GTUI thread, manipulators and main thread with the default fps monitor. So far I have noticed that it seems to happen in the fbw a320neo, default 787-10 and horizon sim 787-9. It does not happen in any other addon aircraft that I use (Fenix a320 and pmdg 737). It seems to be linked to the avionics/displays or systems in some way. For example when the screens turn on or update in some way there is a spike. It also happens when pressing some switches or buttons. I tested it by repeatedly spamming the master caution button in the 787 and everytime it is pressed there is a spike. I uploaded two screenshots of the fps monitor. First one is when sitting idle. and the second one is with battery and ground power on while spamming the master caution button. I am using dx12 and Frame generation. What could be causing this?
Specs:
Ryzen 7 7800x3d
32gb ddr5
RTX4090
Samsung 990pro ssd(1tb and 2tb)
I see this also. I’m flying the 787 a lot lately and also increasing the ND range knob (to 160 or 320nm) causes these spikes and stutters. This is with Framegen off and on the case.
I’m also using dx12.
I have been having the same problems with my RTX 3070ti flying 90% in the UK My specs are mid range
Ryzen 7 5800x 32gb ram RTX3070ti M.2 storage:
I was having having issues with my FPS starting at around 45FPs and the 99%FPS at about 40FPs I was at GA Airports mostly BBD but I have some ORBX software. After about 15 mins of flying my FPS would be the same at about 42 - 47FPS but the 99% FPS would drop to single figures 7-9 FPS giving a massive stutter every 0.5 sec.
I read lots of online stuff about changing my Page Files and Virtual memory but thought I would start with something simpler.
So I removed everything from my CF and low and behold it fixed it. Next I slowly put back my CF addons and found the culprit to be my ORBX British Isles Mesh scenery. Maybe having GB central and GB south and the British Isles mesh screwed it up (probably). I have now removed the British Isles Mesh and I am happily sitting at 45FPS with the 99% FPS just below at 40FPS which I think is where it should be. Hope this helps someone out there.
Further to my previous post, I apologise to ORBX nothing wrong with your software My GB Central and South are fine my problem lay with an aircraft I was using. Intermittently I was using the JP Logistics C152 and this was causing issues with my PC. I would swap to another aircraft and and sim would work fine hence me getting confused. But I put the ORBX software back on and flying the JPL C152 and it would break again. Just had a long flight 1.5 hours on VATSIM with all my software back in the CF and flying the JF PA28 and no issues. I am so happy I could cry…
