Guide will be left as is until release,
Here is a detailed analysis of each setting’s visual and performance
impact. I’ve benchmarked the effects of multiple different settings in
a sterile scenario.
This guide is supposed to help you make decisions on visual impact versus CPU / GPU impact in the
simulator.
System Specifications:
i7 6700 BCLK overclocked to 4.335 GHZ
24GB of 2890MHZ CL16 DDR4 RAM
GTX 1080 at 1974 / 5481 MHZ
Windows 10 build 2004.
Nvidia drivers 451.48 with HAGS On.
MSFS Client + Packages is installed on a 7200 RPM drive.
Test areas usually pre-cached once with a separate 7200 RPM RAID array.
What is HAGS (Hardware Accelerated GPU Scheduling) and how do I enable it?
Hardware Accelerated GPU Scheduling is a new feature that optimizes GPU scheduling (which is usually
done on the CPU) by offloading it to a “GPU based scheduling hardware” on the graphics card itself.
You require a Nvidia 10 series or newer / an AMD RX 5600 - 5700 series GPU in order to use this.
Enabling procedure:
1. First, update your graphics drivers to latest.
2. You need at least Nvidia 450.98 or AMD 20.5.1 Beta to enable this feature. (AMD 20.5.1 Release or
20.7.1 Release lacks HAGS support as of now)
3. Then follow this guide 349:

Testing Methodology
Testing Methodology
Screenshots are mostly taken at GPU Bottleneck settings with some exceptions.
Framerate numbers are captured by MSI Afterburner.
GPU usage and VRAM usage numbers are taken with a reasonable average through MSI Afterburner
CPU usage numbers are only eyeballed numbers through Process Lasso and thus only referred to roughly
from notes.
If a setting seemingly requires a restart to take effect, a standardized position will be selected.
CPU and GPU dependency of a setting is determined by comparing CPU bottlenecked settings and GPU
bottlenecked settings in the same scenario.
Traffic settings were benchmarked with only the tested traffic setting enabled.
Testing Scenario
Multiplayer: Off (Group Only)

Foreword:
Fullscreen typically nets you the lowest performance loss as the game does not have to pass through DWM,
or in the case of UWP apps, it usually utilizes a different display model.
HDR is known to potentially impact framerates on Nvidia cards, moreso if G-Sync is enabled.
V-Sync is recommended to be disabled unless you can constantly maintain the same framerate as your
display refresh rate, otherwise there will be frame pacing issues.
G-Sync reportedly has framerate issues with majority of MSFS builds (including 1.6.11)
Some settings were benchmarked at larger increments (eg. AF 0x, 4x, 16x only) to save time.
Always set “Full Screen Resolution” to your native monitor resolution, and tweak rendering resolution
with the “Render Scaling” slider. This ensures lowest input lag, and the UI will be as sharp as possible.
Note that some settings are tested on old versions, and other versions may behave differently both
visually and performance wise. Full retest will come with the release of Closed Beta
Recommended Settings
This is to be taken with a grain of salt as it is for the people who do not have the time to go through the
individual settings analysis posted below.
I highly suggest you do go through the individual settings analysis as CPU / GPU balance as well as personal
taste can vary.

Recommended Setting: TAA
Performance Impact:
No impact on CPU performance.
Off, FXAA, DLAA gives 34 FPS
TAA gives 33 FPS (3% reduction)
Visual Impact:
Geometry aliasing is visible in motion on Off, FXAA, and DLAA, which is not present in TAA.
– TAA removes this aliasing at the downside of motion artifacts and ghosting.
I highly reccomend using TAA as it is the main denoiser for Ambient Occlusion, and Reflections, and as
such these effects will not be displayed properly unless TAA is enabled.

Recommended Setting: 100
Performance Impact:
This setting impacts both CPU and GPU performance as it is increased.
Under a CPU bottlenecked scenario,
10 at 110 FPS
100 at 98 FPS (11% reduction)
200 at 88 FPS (20% reduction)
Under a GPU bottlenecked scenario,
10 at 42 FPS
100 at 38FPS (9.5% reduction)
200 at 36 FPS(17% reduction)
Visual Impact:
Linear quality increase up to 100, but going past 100 leads to lower framerates with smaller visual
impact
*Tessellation Quality
Recommended Setting: Ultra*
I was unable to get screenshots or benchmark tessellation quality in the sim specifically. Tessellation
generally runs at an extremely low cost on modern GPU’s (Nvidia 900 series or newer), but a heavy cost on
older GPU’s (Older than Nvidia 900 series).
If your GPU is 900 series or newer, I recommend tessellation on Ultra, as there will be likely little
performance impact.
If your GPU is older than 900 series, I recommend lowering the tessellation value or turning it off
completely.
Please reply to the thread if you know where terrain tessellation is displayed.

Tested at KJFK 31L, only CPU-limited settings benchmarked, TBM 930
As you can see from the following three graphs, the game does not heavily scale in both FPS and loadtng
times past 8 cores and 8 threads, and performance even potentially degrades at 8c16t due to overhead caused
by SMT.
I recommend a CPU with 8 physical cores minimum for MSFS at it’s current state.
Hardware Accelerated GPU Scheduling
Tested on Closed Beta Preview 1.6.11.0
Typically, HAGS gives performance boosts of around 2-3% 3 in most games.
From my testing at KJFK, I got 18fps when GPU bound at 34fps when CPU bound, with HAGS on or off
(there was no difference).
However from a past thread 11 by @OperatorLand468, it is shown that frametimes are much more stable
with HAGS enabled.
This does come with the tradeoff of pop out panels not working with HAGS enabled though.
Turn on if you want more stable frametimes, turn off if you want pop-out panels.
Wishlist to Asobo:
Comparison images between Low and Ultra built directly into the sim (see Ghost Recon Wildlands,
Watch Dogs 2)
Ability to adjust post process shaders currently applied in the sim (such as sharpening, eye adaptation,
bloom strength)
Tips on CPU / GPU impact on performance (see Forza Horizon 4)
Better denoising / accumulation on SSR and SSAO
Clearer image with TAA
