closedAnti-Aliasing SSAA-Difference between OpenGL & Direct3D
0%
Description
The anti-aliasing effect with SSAA is different between OpenGL & Direct3D when you use a native resolution and 8x SSAA. With Direct3D the anti-aliasing effect is smoother then with OpenGL.
Currently, i use the Dolphin Version 4.0-8342
What are your PC specifications? (CPU, GPU, Operating System, more)
i7-3770K, ATI Radeon HD 5870, Windows 7 64-Bit
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
I made 3 Tests with Direct3D and OpenGL and have made screenshots which you can find here. The files has the prefix "Test1", "Test2", "Test3".

very interesting, i noticed a scaling bug with D3D antialiasing (on my GTX970) -there's some error that leads to staircasing effects: https://bugs.dolphin-emu.org/issues/9107
which game have you tested? i'd like to try it
do you want to take look/screenshot F-Zero for a comparison?

This should be fixed by 4.0-8462. Can anyone confirm that?
The link to 4.0-8462 is https://dolphin-emu.org/download/dev/294bb753164b58eb0a1e9317eaf05ce3d5bb0209/, but that download isn't available for Windows. The closest available build is https://dolphin-emu.org/download/dev/8843760ad72fa19d72c53607f27313c88ab864a1/

I tested it on Mario Party 8 (RM8P01)

I've tested it with F-Zero GX (GFZP01) and Dolphin 4.0-8534, Direct3D, SSAA 8x, XFB-Enabled (real). I could not reproduce your issue (see Sreenshots, all is fine).

- Status changed from New to Working as intended
Its up to the driver to determine how to downsample. Not our issue.

No painroblem. When i made this ticket, OGL had fewer issues as D3D,so i wanted to use it. But meanwhile D3D has become better and independent from that, D3D is faster on AMD :)
