Huge thanks to everyone that helped get this release ready, over 4 years in the making.
The PCSX2 Dev Team wishes everyone happy emulation with the new release.
The below is a list of highlights, see each respective progress report.
At present we only have the new Windows Installer and Binary available however Linux users can compile from source by following this guide.
Q3,Q4 2019 - Q1 2020 Changes
Q3-Q4 2019, Q1 2010 progress report highlights, read the full report here
GSdx-HW:Improve search/invalidate texture in render target by correctly matching vertex offsetted draws with buffer offsetted reads in the texture cache.
GSdx-HW:Implemented Software Sprite Renderer feature which allows to CPU emulate (SSE accelerated) certain sprite draws directly from the HW renderer.
GSdx-HW:Added a dedicated fix for Big Mutha Truckers which allows to render the shadows properly. This also allowed us to reduce the crc hack level so there are less effects skipped.
GSdx-HW:Sprite Hack has been completely removed as it is no longer needed and is replaced by far better alternatives.
GSdx-FX:The TFX shader on Direct3D10/11 has been rewritten to match OpenGL code and its' accuracy for certain effects.
GSdx-D3D:Blend no Barrier support has been ported from OpenGL to Direct3D 10/11.
GSdx-GUI: Hardware hacks GUI has been updated for better usability.
Fixed the noise generator outputting 4.8 kHz tone instead of white noise.
PCSX2 now ignores non-existent disc sector reads.
PCSX2: Prevent the UI from hanging/locking up when a game boots.
PCSX2-tas: TAS Recording functionality has been disabled for 1.6 release as there are some issues to work out (such as hanging/locking up the emulator).
PCSX2: DI execution is delayed by one instruction.
PCSX2:Reverted back to older VRender/VBlank timings.
PCSX2: Partially fixed IPU pack command.
PCSX2:Fixed the emulator hanging when pressing F4 too fast when toggling the Frame Limiter in some occasions.
PCSX2:Fixed the emulator hanging when pressing F9 to toggle rendering between Hardware and Software in some occasions.
PCSX2: Fixed the emulator hanging when pressing F9 to toggle rendering between Hardware and Software mode too fast.
PCSX2:First Time Wizard now properly selects the correct GSdx plugin based on the highest instruction set supported by the CPU.
PCSX2: Improved pointer patch command handling.
PCSX2 GUI changelog
