The only thing that i do to at least get in to the sim, is to delete Nvidia NGX file and start the sim in safe mode. Works only once. And only in DX12 mode... When i leave the sim and try to start it up again, the same thing happens... The sim kicks me out after loading 50% of the blue bar...

So you deleted current driver with DDU and installed 566.36 with no success? If so a complete reinstall is in your future I suspect. If not you’re missing a critical troubleshooting step IMO. Good luck, YMMV TANSTAAFL -B

August 14, 2025Aug 14 No problem here. I fly in MS2024 most of the time, but today I cranked up MS2020 and it loaded and works fine as far as I can tell. Must be a server issue.

August 14, 2025Aug 14 Author Finally got the sim up and running!!! 👍😃👍 Dont ask what and how i did...been working with this issue the last 12 hours...🙄 And suddenly, it worked! BUT, i can for some reason only run in DX12 mode... In DX11 I get kicked out...☹️ The sim runs fine now! So far...😬 But what is the exact difference between DX11 and DX12 in msfs 2020??? is it good/better in DX12? I dont see much difference anyhow... But what is the difference? Best regards and thank you sooo much for all your help and engagement! 🌹
August 14, 2025Aug 14 Try deleting your UserCfg.opt file and boot the sim. The file will be recreated by the sim but you will need to set your graphics settings the way you prefer it. This worked for me last week.
August 15, 2025Aug 15 OK.. just a few suggestions here.. Did you check the Event Viewer to see what the faulting module was? This will lead you down the right path.... Ive been recently having major issues with a forced windows update (which has affected many KB5062660) which for some reason doesn't certify NVIDIA GPU area when called on.. so get BSOD... im hoping you aren't affected by that.. But post your event viewer description and the ID number and we can go form there to help... i9 13900KF @ 5.5Ghz | MoBo MSI PRO Z690-A WiFi | Corsair Vengeance Black RGB RS 64gb DDR4 3200MHz | MSI GeForce RTX 5090 Vanguard SOC 32GB | MP33 Pro 1TB M.2-2280 NVME SSD for OS | Samsung 870 QVO 2.5" 4TB SSD SATA2 | Samsung 990 PRO 2TB | Corsair RM1000X 2021 1300W 80 Plus Gold PSU | Antec Dark Fleet DF700 Flux Gaming Case | Win 11 home | Samsung 65" 4K TV | G512 Keyboard | Razer Basilisk V2 Mouse | WinCtrl URSA MINOR 32 Throttle Metal / 32 PAC Metal | WinCtrl Ursa Minor Sidestick |Velocity One Rudder | MiniCockpit FCU and EFIS | WinCtrl MCDU | Stream Deck XL | Tobii Eye Tracker | Pimax Crystal Light | Doug
August 15, 2025Aug 15 Author I got the sim running in DX12, but with less performance and stutters... And when i try to set the sim in DX11 mode, it crashes... Anyone know why that is? Regards Per
August 15, 2025Aug 15 Sorry to hear about your issues its a real bummer when that happens. A quick search brought this up from earlier this year: MSFS 2020 Crash To Desktop while loading [SOLVED] - Discussion Hub / General Discussion - Microsoft Flight Simulator Forums Apologies if anyone else has already flagged this, but it seems this guy had a similar sort of problem. They had an issue with their antivirus, where the process remained active and caught the flightsimulator.exe and quarantined it on loading as if it was a virus. In that case I assume you would have to add the simulator to a white list Anyway really hope you solve the problem, and I coudl add it was a really nice to see how members of theis community hhave come to you help from all over the the World.
August 15, 2025Aug 15 Author Its fantastic with all this great help trying to help me solve this, including you! 🌹 I will try to keep trying to fix this with all help i can get! This really drives me nuts as it is right now...😥
August 15, 2025Aug 15 Author What i have discovered so far, is that when i remove the file NGX file in NVIDA file in programdata, i manage to start the sim in safe mode, but not in normal mode... And after that the file i deleted in NVIDA, the NGX file is back again... Im going crazy! 😥
August 15, 2025Aug 15 Author And also... When i deleted my community folder, i can start the sim once... In normal mode. But when i shut the sim down and start it up again, i get kicked out... I give up... With teras in my eyes... Dont know what to do. I have tried everything you guys have told me, and nothing seems to help... 😥😥😥
