It's Direct3D itself which does this, and madVR can't prevent it. Usually, Direct3D is supposed to keep the current mode, but that doesn't always work. If all else fails, I suppose you can disable the "automatic fullscreen exclusive" mode, that should take care of the mode switch. Other than that, I'm sorry to say, but I can't stop Direct3D from changing the display mode. Direct3D doesn't allow me any say in this. |
|
|
This only happens with madvr; if I use the Enhanced Video Renderer (custom presenter) by MPC, the display mode is not changed. |
|
|
Even in EVR "fullscreen" mode? Do you have the option "use D3D11 for presentation" active in madVR? If so, does the problem also occur if you deactivate it? |
|
|
Yes, EVR has no issues with fullscreen. The option "use D3D11 for presentation" is disabled. Disabling "automatic fullscreen exclusive" the display mode stays untouched. |
|
|
Yes, D3D likes to switch display modes when you enter fullscreen exclusive mode. At least D3D11, not totally sure about D3D9 right now. |
|
|
Ok, thanks! I will keep "automatic fullscreen exclusive" disabled; how much will I lose in terms of performance? |
|
|
The performance loss should be minimal. FSE mode (fullscreen exclusive) is just more reliable in terms of avoiding frame drops. But for many Windows 10 users it works just fine without FSE mode. With Intel GPUs you'll lose the ability to send 10bit to the display, though. But it's not a big deal, because madVR's dithering has very high quality, so 8bit is sufficient. |
