1. TURN ON HAGS: Windows Settings - Display - Graphics - Default Graphics Settings - Hardware-accelerated GPU Scheduling ON!!!! (And you have to restart your PC if it was not enabled)!

2. CREATE A WINDOWS RESTORE POINT.(ALSO CONSIDER A MANUAL BACKUP OF THE FS FOLDER. THE FOLDER IS ABOUT 2 GIGABYTES )

3. RECOMMENDED (NOT MANDATORY): 
a. MANUAL BACKUP OF THE FS FOLDER. THE FOLDER IS ABOUT 2 GIGABYTES
b. MANUAL BACK UP OF WINDOWS REGISTRY (INSTRUCTIONS AT https://support.microsoft.com/en-au/topic/how-to-back-up-and-restore-the-registry-in-windows-855140ad-e318-2a13-2829-d428a2ab0692#:~:text=In%20Registry%20Editor%2C%20locate%20and,Select%20Save.
c. RESTRICT MAX FPS TO 60 IN NVIDIA CONTROL PANEL. 

4. GO TO NEXUS MOD SITE https://www.nexusmods.com/site/mods/738?tab=files (THERE SHOULD BE 4 FILES IN THE "FILES" TAB

5. DOWNLOAD "dlssg-to-fsr3-.90" ZIP FILE (or latest version) FROM NEXUS MODS

6. EXTRACT THE ZIP FILE 

7. OPEN THE README FILE IN THE UNZIPPED FOLDER

8. FOLLOW THE INSTRUCTIONS IN THE README FILE:
a. Double click on "DisableNvidiaSignatureChecks.reg" and select "Run". Click "Yes" on the next few dialogs.
b. Copy "dlssg_to_fsr3_amd_is_better.dll" and the new "nvngx.dll" to your game's installation folder (FOR ME THIS IS D:\SteamLibrary\steamapps\common\MicrosoftFlightSimulator...FOR MOST USERS, DEFAULT PATH IS C:\SteamLibrary\steamapps\common\MicrosoftFlightSimulator)

9. REBOOT PC

10. IN NVIDIA CONTROL PANEL, IN 3D SETTINGS FOR THE FLIGHT SIMULATOR, DO ONE OF TWO THINGS....EITHER ENABLE VSYNC, OR SET IT TO "FAST". I PREFER FAST, AS IT EMULATES VSYNC WITHOUT ALL THE ISSUES. THIS IS NEEDED BECAUSE THE WAY THE MOD WORKS WILL PROBABLY CREATE SCREEN TEARING, BUT VSYNC NEEDS TO BE DISABLED IN GAME SETTINGS.

10. START MSI AFTERBURNER TO SEE INGAME CPU/GPU USEAGE, AND LAUNCH FS2020, THERE WILL BE POPUP MESSAGES. CLICK THROUGH THEM (NOTE: I RECIEVED NO POP UP MESSAGES)

11. GO TO OTIONS/GRAPHICS. ENSURE DX12 IS SELECTED. YOU MUST BE USING DX12 FOR THE FRAME REGENERATION TO WORK.  ONCE DX12 IS SELECTED (MAY REQUIRE REBOOT OF GAME) SEE IF THE OPTION "NVIDIA DLSS FRAME GENERATION" IS AVAILABLE AND NOT GREYED OUT..(MINE IS NOW ENABLED...THE DESCRIPTIONS SAYS IT'S FOR NVIDIA RTX 40.. GRAPHICS CARDS, BUT IT SHOULD NOW BE ENABLED, NOT GREYED OUT).. SET IT TO "ON". ENSURE VSYNC IS OFF, REPEAT.... VSYNC MUST BE OFF. REBOOT IF NECESSARY.

12. TEST FLY AIRCRAFT....AND USE MSI AFTERBURNER TO JUDGE EFFECTS.
