the best way to eliminate stuttering is to lock FPS (using GPUTweak or similar is easy, or the GPU Native Control panel max framerate between 36-45). One Frame lower than your avg. FPS rate. This stops the GPU from bottlenecking the CPU with unnecessary work. I fly in VR, so I need about 36FPS, then the Quest2 headset uses Spacewarp (inter-frame filling tech) to give my headset 72FPS. I see crystal clear textures on houses and buildings in New York or Los Angeles looking down my 9-line (along the left wing) at 600ft doing Mach 1… while live streaming on an 8700K 4.1ghz OC on a 3090ti all water-cooled. If i turn objects up to 200, i get warp-stuttering as my Wireless network performance starts tugging on the Quest2 wireless network traffic. Stuttering using a direct RIFT cable is different than wireless. I got stuttering on my 5 year old windows 10 system on HDD, but now its butter smooth on SSD fresh OS. There are many points of failure, most being overheating. Pro tip: your CPU heatsink installation being LEVEL is important and most don’t know if theirs is OPTIMAL. Then there’s the silicon lottery. I’ve tweaked every single setting on my PC running COD, ASSETTO, DCS, FORTNITE, etc. and ensured my system idle LATENCY was low. (use a latency monitor to check) Audio exclusiveness and audio enhancements, ARGB lighting on ASUS motherboards uses software that consumes 20% of the CPU (if you have 12 fans like me). Power supply can starve the GPU, etc. etc. etc. etc. so many things. I learned that my XMP 3000mhz RAM runs optimal at 2133mhz after googling it. easiest BIOS adjustment ive made, besides telling the 95watt CPU to only run at 70watts at stock frequencies, to help track down stutters. To verify Run any video with predictable animation and bench the CPU using CPUZ, watching for stutters. LASTLY, watch the intro to MSFS closely… the loading screens will stutter if your thermal throttling or have resident background software latency issues. The Sim DLSS and other settings are showing you the door early.
I get poor performance using DLSS and LOVE TAA in VR with my Quest2, but the QuestPro is soooo clear, i have to turn OFF Antialiasing, especially at night. Daytime I like TAA at 80 percent.
P.S. my 6700K gets better performance than my 8700K because of ARGB software.
