September 28, 20223 yr Commercial Member Hello all! Here are my findings with unlimited FPS to test. Seems like DX11 is better for me. Also using TAA with a LOD of 150. With that I can almost be stutter free. My goal is to lock frames to 40fps. i9-9900K OC to 4.8GHz - RTX 3080 Fenix A320 + LatinVFR KFLL + Ian (Hurricane) Inside Virtual Cockpit + Outside View Edited September 28, 20223 yr by iFlySimX Discord | YouTube | iFly Schedules 34" Odyssey OLED G8 175Hz | 3440X1440 | AMD Ryzen 7 7800X3D | PNY VERTO OC GeForce RTX 4070 Ti SUPER 16 GB | G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL30 | Asus ROG STRIX B650E-F GAMING WIFI ATX AM5 | Samsung 990 Pro 2 TB M.2-2280 PCIe 4.0 X4 | ARCTIC Liquid Freezer III 56.3 CFM Liquid CPU Cooler | Fractal Design North XL ATX Full Tower Case
September 28, 20223 yr So higher fps with DX11 - but is it more smooth? Btw there's already several threads on this... 7950X3D | RTX 4090 | 64GB DDR5

No, I find DX11 more smooth...

September 28, 20223 yr My findings are similar, I gain an average of 5 fps from DX11. The sweet spot for me is also to lock it to 40 fps. Smoothness, if 40 fps is maintained, is the same in both DX11 and DX12, obviously if I go to a heavy scenery, I will start having stutters (minor) first with DX12 since it gives me 5 fps less. i9900K @ 5.1GHz HT ON - GTX 1080 Ti SN737
September 28, 20223 yr Similar findings here also, though the cost of DX12 seems to vary depending on complexity... with less difference between DX11 vs DX12 with more complex settings and aircraft. That said, DX12 is very smooth.

However, what I don't understand is given the above information, from where is this 20msec calculated from when the longest individual thread time is 18.8msec, equating to ~53.2fps ? So is it the total of more than one of the thread times, which, when summed together give 20msec ?
September 28, 20223 yr one starts to wonder whether Asobo's effort in DX12 enhancements is really worth it or not.

Oh yes, I believe the issue is more with Nvidia than with DX12. When I had an AMD card, in every game where it was available, DX12 or Vulkan performed better than DX11. Will probably switch back next gen. Xbox has AMD hardware as well... Laminar Research customer -- Asobo/MS customer -- not an X-Aviation customer - or am I? 😉

Asobo has invested a lot on these enhancements, so I expect more improvements in future updates 38 minutes ago, Ianrivaldosmith said: Totally worth it when you have modern hardware to support it… way smoother. I have a 3090 GPU and I still find that DX11 + TAA yields the best results with regard to visuals and performance (smoothness). DX12+DLSS presents some strange glitches (moire effect) on certain objects and some water patterns.

September 28, 20223 yr Dont forget it is still a Beta DX12 driver so hoping for more in the future. At the moment not useable for me a lot of issues with this driver in DX12, have still those graphikel artefacts - should that not be fixed with 517.XX ? DX11 with DLSS seems to work OK with my Rig but still have to do more testing.. cheers 😉 08.2024 new PC is online : ASUS ROG STRIX X670E-F GAMING WIFI Mainboard, AMD Ryzen™ 9 7950X3D Prozessor, G.Skill DIMM 64 GB DDR5-6000 (2x 32 GB) Dual-Kit, MSI GeForce RTX 4090 VENTUS 3X E 24G OC Grafikkarte, 2x WD Black SN850X NVMe SSD 4 TB - Drive C+D, WD Gold Enterprise Class 12 TB for storage HDD, Thermaltake Toughpower GF3 1000W PC - Power supply, Thermalright Phantom Spirit 120 EVO CPU Aircooler with 7 Heatpipes, Design Meshify 2 White TG Clear Tint Tower-Case, 3x 4K monitors 2x32 Samsung 1x27 LG 3840x2160, Windows11 Prof. 23H2 - now Windows11 Prof. 25H2 Flightsimulator Hardware: Honeycomb Throttle Bravo, Logitech Extreme 3D Pro, Logitech Flight Joke System, XBox Controller, some Thrustmaster stuff, Winwing CDU Panels.
