February 22, 20233 yr Are you using Frame Generation? Rhett 7800X3D ♣ 96 GB G.Skill Flare ♣ Gigabyte 4090 ♣ Crucial P5 Plus 2TB
February 22, 20233 yr What is your terrain lod? If it is greater than 200, it seems normal for nyc without frame generation. C. Uygar Aircraft Maint. Engineer. at LTFJ
February 22, 20233 yr 30-35 FPS sounds about right when you are using AI traffic. Tested just now myself. Ryzen 9 5900X RTX 4090 DX 12 Ultra Preset in 4K with TAA (No Frame Generation) Loading the PMDG 737 on RW 13 at KLGA I get 50 FPS. When I start FSLTL Traffic it drops to 30-35 FPS after injecting a total of 100 AI planes and they all start moving. You can try playing around with the settings, but the only things where I can really improve the Main Thread limited performance are the LOD sliders. Some other things like disabling Nvidia Reflex and Glass Cockpit Refresh Rate will give you maybe only 1-2 more FPS each. You can enable Frame Generation to ~double your FPS, but I don't like it in MSFS, at least with head tracking I get some shimmering with text on displays.

If there is anything we have learned over time, it is that any computer can be brought to its knees by a combination of scenery addons, airplane addons, weather, traffic, and graphics settings.. You may just be bumping up against the limits a bit... 30 fps aint that bad 😉 Bert

April 30, 20242 yr Please help me. Less than 10 fps due to "Limited by Main Thread" after changing MB (Intel B75) with a RTX 3060 TI, Intel I7 3400, 16 Gig RAM. What should I try?
April 30, 20242 yr Intel B75 chipset? These are from 2012, aren't they? Can you write down your complete system specifications?, like which CPU you have? I can't find anything about an Intel I7 3400 CPU. Which generation is that? If the CPU is also from 2012 than there-in lies the problem: it is much too slow for MSFS. No matter what videocard you use, the CPU cannot handle it unless you turn down graphics and especially AI aircraft.

May 4, 20242 yr Thanks for your help...

May 4, 20242 yr The MB is new, a made in china (Kllisre-B75 ), same especs the failed old one (Taicon), also made in china that let me run the MSFS with 30 fps steady.
May 4, 20242 yr 4 hours ago, hpdc_br said: CPU: Intel® Core™ i7-3770 CPU Unlike most games, MSFS is not GPU dependent. Rather, it's very CPU intensive. The minimum specification for MSFS is an Intel i5-4460. Recommended is an Intel i5-8400. https://flightsimulator.zendesk.com/hc/en-us/articles/360013463459-Minimum-Recommended-and-Ideal-PC-requirements-for-Microsoft-Flight-Simulator (Though I'd argue that those CPUs still aren't strong enough for MSFS). Your RTX 3060 Ti is wasted on the rest of your PC. When you have sufficient funds, get a new CPU, motherboard, DDR4 or DDR5 RAM (depending on chipset) to balance everything out. Don't forget that the speed of your Internet connection also matters.
