Some things to play with in the settings, as the presets are kind of wack:
-
The Data / Online settings can cause stutters due to connectivity, even though the app is meant to fall back gracefully. To narrow it down try switching OFF at Options / General / Data (tab) / Online Functionality. Usually it’s the ‘Live Real-World Air Traffic’ causing issues, but switch them on one by one to see.
-
The Aviation Traffic has a LOD bug that eats VRAM. Again, to narrow it down, try flying a Flight Set-up with no Multiplayer / AI traffic. The ‘Flight Conditions’ page should look like this:
- The vehicle buzzing around default values are too high for 16GB of RAM. Try turning down Airport Life and Land and Sea Traffic down to 20 (from 50).
-
MSFS due to the way its Rolling Cache works is really susceptible to Virus Checkers causing frame jitters. Try putting an exception in for MSFS file locations or turn it off to narrow things down.
-
The Rolling Cache is a bit buggy, and can cause frame drops. Try turning it off if you don’t have an internet cap. It’s here at the bottom (your data usage will grow, depending on where you fly), but you can view a tracking total number on it:
-
For a 1070 try the Anti-Aliasing set to FXAA.
-
If after all the above things don’t help, knock the Options / General / Graphics / Render Scaling down to 80% - most people are hard pushed to see the difference and it helps a lot on VRAM.
-
If you are on Win10 2004, and using a latest driver, try enabling Hardware Accelerated GPU Scheduling (HAGS). Right button on your desktop for ‘Display Settings’, scroll to the bottom for ‘Graphics Settings’ and you get to a screen where you can flip HAGS on if it’s enabled for your combo of hardware.
-
A graphics setting that is adjusted by the presets, but is worth experimenting yourself, is the Terrain Level of Detail slider and the default ‘Trees’. These two things have a big impact, so try bringing down the LOD to 10 or 20 if you are still struggling. The trees actually look better on ‘Medium’ anyway(* I’ll do a separate post fo that):
- Nobody can really run Ultra at 4K comfortably. It’s good for screenshots until we get huge VRAM GPUs. The sim looks great on ‘High’ with a good PC, and pretty nice down from that.
