I got it working on my Pro 3 i5 running Windows 10 by using dxcpl.exe to limit Direct X to 11.0 and 'Force WARP' then running it Windowed.
It gets to the main menu and even manages 30-40 FPS at 1280x720 on Low settings in the menu. But as soon as I get into the game it is unplayable.
I originally thought it was the thermal throttling causing it - which was definitely correct to a degree.
I obtained a USB fan to eliminate this which was successful and proven by running benchmarks and using Intel ETU to show thermal and power throttle.
Sadly it hasn't changed my Fallout 4 experience!
My CPU hits and stays at 100% with GPU load at 1% and an almighty 1 FPS.
Have tried all the tweaks others have tried and published:
- Using the latest Intel sourced drivers over the Microsoft ones
- Setting the Intel graphics properties to Maximum
- Using the High performance power settings
- Running the game in Windows 7 Compatibility mode
I am really struggling to address this issue, it doesn't happen on the Pro 3 i7 either!
