Below you can see my findings of testing the various configurations I have in relation to my Display driver settings. My WinUAE setup consists of two scenarios I use frequently.

Scenario 1, Games setup (OS3.1 RTG, WHDLoad)

Goal of this setup: proper framerate on Native display using D3D11 in combination with Low latency VSync

- Intel HD settings: 50p Hz

The following two combinations work as desired (work as desired = above mentioned goal reached):
1. Full screen, 720 x 576 with setting 'Default refresh rate', Triple buffering on Host Display tab
2. Windowed, 720 x 576 with setting 'Default refresh rate', Triple buffering on Host Display tab

- Intel HD settings: 60p Hz Refresh Rate

The following combination works as desired:
1. Full screen, 720 x 576 with setting '50Hz PAL', Triple buffering on Host Display tab

The second combination doesn't work as desired:
2. Windowed, 720 x 576 with setting '50Hz PAL', Triple buffering on Host Display tab

Setting the Refresh rate on the Host Display tab doesn't seem to cause a change, both default and 50 Hz PAL cause an increase in speed (sound output has a higher pitch). Is this related to the 'Windowed' setup? Is it not possible to change FPS in Windowed mode?

Looking at the above situation, there is a solution for this issue: put the Intel HD settings on 50p Hz. Unfortunately this causes some bad side-effects for my second scenario:

Scenario 2, Productivity setup (OS3.9 RTG, 68060, Toccata, etc.)

Goal of this scenario: proper sound output on RTG display

- Intel HD settings: 60p Hz

The following two combinations work as desired:

1. Windowed, 1024 x 768 with setting 'Chipset', Double buffering on Hardware RTG board tab
2. Full screen, 1024 x 768 with setting 'Chipset', Double buffering on Hardware RTG board tab

Sound output: OK

- Intel HD settings: 50p Hz

The following combination works as desired:
1. Windowed, 1024 x 768 with setting 'Chipset', Double buffering on Hardware RTG board tab

The second combination doesn't work as desired:
2. Full screen, 1024 x 768 with setting '50', Double buffering on Hardware RTG board tab

Sound output: NOK. Better than having the setting on 'Chipset', Double buffering on Hardware RTG board tab (which causes a real slow-down in sound output), but still 'cracks' are heard with peaks in volume.

To conclude my findings:

- For the Games setup, the Intel HD settings: 50p Hz is perfect
- For the Productivity setup, the Intel HD settings: 60p Hz is perfect

Is there a possibility to have perfect conditions without touching the Intel HD settings? What do you need from me to be able to investigate should something go wrong?
