Increase the AccuracyBlending level to Medium or High. If the issue persists, switching temporarily to the Software renderer will fix it entirely. The Evolution: Where is GSDX 11 Today?
To further enhance image quality, GSdx includes several options to smooth out jagged "jaggies" on the edges of 3D objects. It offers FXAA (Fast Approximate Anti-Aliasing), a post-processing effect that is relatively light on performance, as well as other shader-based anti-aliasing techniques.
In PCSX2 1.7+ (nightly), Vulkan often surpasses D3D11 in both accuracy and speed.
The plugin system was abolished to improve stability. Settings Location: Go to Settings > Graphics .
OpenGL is generally better for Linux and some AMD cards but can be slower than Direct3D 11 on Windows.
