What should happen?

PPSSPP not crash after switch to Direct3D 11 backend. :)

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

Windows 7 64 bit CPU: Intel Core i5 M460 GPU: Intel HD Graphics (OpenGL 2.1)

PPSSPP v1.8.0 Build 157

Actually what should happen it should not allow you to select that backend since your graphics chip doesn't support d3d11.

Found two cases in the D3D11 init code that could fail, #12041 will likely fix this.

Test on Windows 7 (32 Bit) This issue still exit. PPSSPP crash after switch to D3D11.

PPSSPP v1.8.0-222-g139f39239. d3d11

For Windows 7 (64 bit) I report into the first post, Is my friend's computer, I waiting for an answer from him.

@Saramagrean the issue seems to be not that the emulator crashes, but rather that the emulator allows you to pick and run DX11 GPU code in the first place. The internet suggests your chipset does not support running DX11 code, only DX10.1 or OpenGL 2.1 at best

Edit: fix link

I got it, LunaMoo said that before. I should close?

hrydgard commented 5 years ago

No, it's still an issue. Just maybe not a critical one.

Some Intel GPUs (as 96x series' chipsets) are crashed, due to direct X 11, which aren't supported.
