Ok Guys, Now on FF A320 I got 45-50 FPS inside 3D cockpit. Daytime (not too much clouds however but complex airport with moving vehicles). Settings are: Visual effects : 1 notch from match -> HDR (not HDR+SS0) -> this last notch just bottlenecks it. The FPS then are still acceptable around 35 but panning around seems much more stuttering (not FPS related I think, must be something else). Texture Quality : maximum AA : 1 notch from max -> 4xSSAA+FXAA (not 8x) -> this last setting is possible, it costs about 5 FPS but I prefer to keep them. I suppose I could get in weathers and sceneries that will eat of some more FPS's and don't want it to become noticeable. World objects: Medium (in the middle). One notch up eats 10 FPS (so, down to 35-40) and all the way up eats another 10 to 15 FPS (so, down to 20-25). Refelction : Off Draw Parked Aircraft : Yes Draw shadows on scenery : No AI aircraft set to : 1 Running on VULKAN rendering. I didn't change much on my PC setup. I only found out that (in overclocking world) the AVX offset parameter (in BIOS) usually requires it to set it to -2 or -3 (as AVX instructions are very intense for the CPU, since they are rare in games people don't mind to lose 200 to 300 Mhz), but I noticed on torture tests (with AVX disabled) and in the SIM that my CPU lowers to 4700 or 4800 whereas the multipliers are set to 50 (5000Mhz) for all 8 cores. XPlane does noet use AVX either. So I put that setting in the BIOS to AUTO (AVX offset). now my cores run steady on 5000MHz. Frame time is now 0.02 (CPU: 0,02 and GPU 0,01 -> so still CPU bottlenecked). I only change to Cesna and leave all else the same the FPS = 85 FPS. I can only dream this FPS for my A320 FF 😞 It feels so realistic on 85 FPS woaw Cheers

@iowahawkeyedave Good idea. I changed my FF A320 aircraft for a Censa and the FPS went from 47 to 119 !!! It could really indicate something is faulty with my A320 plane. Sure the A320 would cut away some FPS. I'd expect 20 FPS or so but not 72 FPS ! CUP frame time now 0,008 and GPU frame time still 0,003. I will dig deeper into it -> reinstalling the A320 perhaps. You state AA is a frame killer but it is set to 1x only (the minimum). @GoranM Yes Vsync is off. Gsync also. @mSparks I'll try the 744 later. Got to solve my issues here 🙂 @Bjoern Tried with Hyperthreading off and Xplane now sits on core n°8 instead of the virtual core n°15. It moved 🙂 I will turn HT back on again as it does no good or harm on XPlane. Cheers all.

Hi fellow simmers, My plugins from the admin page: Navigraph simlink, Betterpushback, Flightfactor Cefloader, Flywithlua; XATC chatter, Xsquawkbox, FF Pluginmanager, TGDS, X-RAAS FF A320, X-TCAS, A320U, FF A320 Ultimate. Only the last two indicate FPS COST: 3,4 FPS for A320U and 23 FPS for FF A320 Ultimate. I have only 50 FPS with ALL SLIDERS WAY DOWN to ZERO (Visual effects Minimal, Text Qual Minimal, Antialisaing 1x, Ainsotropic 1x, World Obj Minimal, Reflection Minimal, parked AC NO, Shadows NO, And what is most funny is that the GPU is like IDLING, it has a frame time of 0,004 (that would be 250 FPS) but the CPU frame time is 0,02 -> which is indeed 50 FPS. I don't get it. This is far from the limit of the CPU (9900K) -> it runs at 5Ghz and is loaded for 18% !? What I do see is that CPU n° 8's virtual thread is running near 100% ... so could it be XPLANE is bottlenecked by the fact it pumps everything through ONE Virtual Core? And yes forgot to mention resolution is 2560 x 1440. Cheers, Olivier

Hi Goran, I will list them tomorrow but it should be something else since my FPS were fine a few days ago and I did not install any plugins. But I will try to remember what I have done in the past few days. And I will let you know. Gr. Olivier

Hi there, I am new here on AVSIM. Right now I am going crazy for something I cannot seem to solve in mij XPLANE 11.50 (running Vulkan). Have CPU 9900K and GPU 2800TI FF A320 cockpit view with ALL sliders set to minimum in the settings and only getting 50 FPS. My CPU frame time = 0,02 and my GPU frame time = 0,004. I guess the CPU is bottlenecking the FPS but how can it be? It's running on 5GHz no throttling, no C state, usage on average is about 25% ... What am I missing here? Tx, Olivier
