All troubleshooting options that have NOT worked:
- Repair Apex Legends
- Uninstalling and reinstalling Apex
- No new Windows 10 updates fix the problem
- No new patches had fixed it
- TdrDelay value
- DDU uninstall and clean reinstall of NVIDIA display drivers
- Rolling back or updating display drivers
- Downloading new Microsoft Visual C++ packages (2015, 2017 and 2019)
- Running both Apex and Origin as administrator
- Running debug mode under help in NVIDIA control panel
- NVIDIA control panel/ Manage 3D settings/ Program settings/ r5apex.exe Power Management Mode: Prefer Maximum Performance
- Steam Apex doesn't work either
- Not even a system reset (Keep personal files) had fixed the problem
EDIT:
Besides Apex, many other games started to experience graphics card-related issues, I got this checked out, and turned out it was a hardware issue. This problem has been solved by getting a new replacement PC under my 1-year warranty.
