Emulator

Games that appreciate Vertex Rounding option for HD gameplay:

• Shadow the Hedgehog
• Silent Hill: Shattered Memories
• Sonic Heroes

My argue is that Vertex Rounding will be disabled for 1x Native anyway. My only worry is whether Vertex Rounding breaks something else more than just a performance hit.

Don't forget to remove the forced 1x Native and Anti-Aliasing settings from Sonic Heroes' GameINI as they are not needed when Vertex Rounding is enabled.
