August 19, 20205 yr I read on another forum that some users are having success by reverting back to their nVidia drivers before the latest update focusing on MSFS2020. I think I will try it.

August 19, 20205 yr What fixed my stutter and smoothness problem was enabling Hyper Threading on my old i7 6700k. Since it's overclocked it runs a bit hot now, but if it dies it dies. There are still occasionally fps hiccups, but are not as severe as they were before and the sim is pretty much smooth. I hope this helps anyone.

August 19, 20205 yr So, I'm really interested in nailing this down and have been doing some testing. I'm curious what others are experiencing, though, because I think we might be talking about a few different things. BTW, I'm looking to compare solutions and settings, not bash the sim. Each sim has required settings finesse to get a smooth experience. It took literally years to understand P3D well enough to run smooth with good visuals. I hope for a shorter learning curve here! So, I'm experiencing periodic stutters, maybe 5 minutes of smooth and then 5 seconds of stutter, that feels like a version of what we experienced in P3D v4.5 - the so-called Orbx scenery loading pause... So for most of the time, I have smooth 30fps performance. When watching the FPS counter in developer mode, I can see that normally my FPS is solid at 30fps and limited by the GPU, which is expected on vsync at 30 hz. However, when I encounter the period of stutter, it shows in the low/mid 20fps and indicates limited by the main thread. I *think* that this is actually impacted by the Terrain LOD setting, but could be the objects LOD also...I was surprised that Terrain LOD was CPU intensive, but it appears to be... below is what the stutter looks like from a performance perspective....curious if this is what anyone else is seeing... don't mind the screenshot quality, it is an HDR issue I guess... 5800X3D | Radeon RX 6900XT
August 19, 20205 yr I got my stutter problems solved! The sim is way smoother and higher FPS. I achieved this by killing lightingservice.exe in my task manager. This is used for RGB lighting on ASUS products, I believe. So crack open task manager and try some things, see what might be causing your stutters. Someone on the MSFS forum said his stutters went away just by opening and switching to task manager but when he switched back to MSFS the stutters came back. Not saying you need to but I did do a re-download/install. This time I made sure the sim went to the same drive. During the Steam install I pointed it to my F: drive and it made a steamlibrary folder there. When it came time to install MSFS I created a folder on the F: Drive named Packages. I also installed the latest NVIDIA drivers again. ASUS Prime Z490-A / i7-10700K / RTX 4080 / G.SKILL Ripjaws 32GB / Lian-Li PC-O11 Dynamic case

Also I'm using a RTX2080 so any theories of this being a 10 series issue aren't 100% valid.
August 22, 20205 yr Just adding this here as it has helped a number of us...the VFR map is rendering even when not open...disable it when you don't need it... 5800X3D | Radeon RX 6900XT
August 23, 20205 yr Offline it's exactly the same for me. The main source of stuttering for me is CoherentGTDraw, linked to the aircraft screens. 7800X3D | 2x32 GB DDR5-6000 CL32 | RTX 5080 | Alienware OLED 34" | 1 Gbps fiber
August 23, 20205 yr Right so here is a weird one. I noticed that a quick way to remove stutters was to put a window in front of the sim. When I was alt-tabbing to perf monitor, all of a sudden my stutters went away, my frame rate stabilised and I was fine. I'm using an AMD Ryzen 5 3600, AMD 5700XT and 32GB RAM with my rolling cache on SSD. This is also a Steam installation. I noticed some frame drop off when I slewed my plane rapidly into new areas of scenery for force a data transfer, but even after the bitrate dropped back down, I was still getting issues. I am assuming there is some form of decompression going on after the download and that this is causing issues. Maybe placing a window in front of the sim deprioritises the work and therefore it does not impact the rendering. God knows! Anyway I so now I run in windowed, rather than fullscreen and it seems to have the same effect. Your mileage may vary. BTW I had already stopped the Lighting service because it had caused issues a few months ago with other programs 😕 Edited August 23, 20205 yr by neilintheus2

CPU is still close to 100% with some micro stutters. Can confirm i was doing fine, updated to the latest nvidia driver at the time of posting (452.06) which made things noticably worse with gpu usage barely above 66%. Rolled back to 451.67 now seeing 88-100% usage and higher and more stable frames. GTX1060 6GB MaxQ

In fact I have found a few things that cause stutters: 1. Loading in new scenery - tried the background job fix, even changed affinity settings, didn't work for me 2. Unstable overclock on GPU - This was my problem, overutilised and peaking too much with no ability to handle it, so reset to factory settings and worked. 3. FSUIPC7 - This seems to be causing stutters, not sure why, but I had to stop using it for FSEconomy. Sure it will get fixed.

I believe that's due to the issues with SimConnect. We'll see how that goes once this stability patch is out. i7 8700K @4Ghz, EVGA RTX3080 Ultra, 32GB RAM, Two 2K displays.
