May 2, 20206 yr Hi guys, i have a problem. I replaced my gtx 1070 to 1080ti. It is normal that my cpu and gpu usage never exceed 40-50% and everytime p3d stutters ? It is a clean install of p3d v4.5 without hotfix 2. My rig : i7 9700k @5,0 ghz 1,3v max temp 74 Msi z390 Plus evga sc2 1080ti - newest drivers installed by ddu; max temp 74 2x16 gb ddr4 g skill ripjaws 3200mhz Navis rgb 360 aio cooler Seasonic gx plus 750w Plextor mpe9g m2 ssd 512 gb addons: fsuipc fslabs a321 orbx global, europe, north america fftf dynamic Active sky with asca freemesh x gsx level 2 tomatoshade without reflection No matter if it is good or bad wheather i cant maintain 30fps stable fps on 4 k res Samsung monitor with 30 refresh rate. Settings in p3d are medium do high. Its weird because cpu/gpu usage is about 50 %, any of cpu cores dont even exceed 80%. In msi afterburner everything seems normal - core and memory clock ok. My test scenario is take off from default klga 33rwy- always stuttery 25-27fps . What can i do? Maybye trying to turn off intel speedstep in bios ? thanks Edited May 2, 20206 yr by darrro87
May 2, 20206 yr Author Dynamic lights on Hdr on Reflection off Autogen draw distance medium Autogen buildings/trees on dense/ no 3 d autogen but ticked high res terrain text Level of detail radius high Texture res on 4096/4 msaa/ vsync plus triple buffering/ monitor set 30hz refreshrate Traffic roads and others off, no ai traffic Mesh 5m Texture 15cm Tes factor ultra In orbx vector only highways I am not i home now so i could cooy nad paste my p3d cfg later Edited May 2, 20206 yr by darrro87
May 2, 20206 yr If the main program thread is maxed out it can look like low GPU usage because the GPU is waiting on the CPU. Usually you will see your core 0 at 100% and the others a lot lower. Remember your CPU usage statistic is a combination of all cores averaged out. You can see how this works by using default P3D settings and observe your CPU GPU usage, then start cranking up all the sliders and at a point your GPU usage will actually drop off.

May 2, 20206 yr Author Lets try to read my topic once again:) My cpu NEVER exceed 100 on ANY of my cores - hw monitor/ msi afterburner. Max is 78% on core 1, core 0 stays about 60%. Thanks anyway
