Yeah it only works in OpenGL not with Direct3D 11 and 12

Gourav111 avatar Nov 21 '25 11:11 Gourav111

Works fine for me with that PR, tested with both D3D11 and 12, on Windows 11.

How to fix D3D11 and D3D12 emulator issue on Windows 11?

I had the same problem on win10, i fuond out that the culprit was the fact i was running at 2xNativeResolution. I went back to Native and that fixed it. Then i set as 2xNativeResolution again and everything was normal as before. I hope that helps you.

After going back to Native resolution as well as 2X Native resolution and with Direct3D 11/12, it won't go fullscreen.

Test with the PR: https://github.com/PCSX2/pcsx2/actions/runs/19556372776/artifacts/4635147319 or just wait until it's "approved" and becomes available in a future update.

I copied the contents into the emulator issue but still the issue persists.

The fix is incomplete and didn't fix exclusive fullscreen, that is currently being worked on

Can you retest https://github.com/PCSX2/pcsx2/pull/13577

TheLastRar avatar Nov 22 '25 00:11 TheLastRar

For Direct3D 11/12

Test fullscreen - Not working Test exiting in and out of fullscreen - Not working Test render to separate window - Not tried Test receiving popups during rendering while fullscreened - Popup is showing but not fullscreen Retest with Render to separate window - Not tried Test if there are new frame pacing or latency issues while fullscreened - Not tried

Can you provide a log for one of the failed full-screen attempts Can you also tell me what Fullscreen Mode you are using?

To confirm, are you using the latest build from that PR (https://github.com/PCSX2/pcsx2/actions/runs/19587382158) and not an earlier version?

TheLastRar avatar Nov 22 '25 05:11 TheLastRar

I am actually using the official updated version which is updated nightly automatically.

Ah, the fix isn't in nightly yet, it's currently being tested in a separate build found in the linked PR/action

Hi, my game wasn't displaying in fullscreen mode due to Direct11. Downloading the regular stable version 2.4.0 from the pcsx2 website instead of the Nightly build helped me. Everything worked fine on it.
