The PSP emulator, PPSSPP [Official Site], recently had a pretty big release which now defaults to Vulkan as the main renderer. They also enabled a shader cache for Vulkan too, which should help smoothen a few games out.

This is great, especially since PPSSPP is free and open source under the GPL and you can check it out on GitHub.

They didn't just work on improving their Vulkan support, as the OpenGL backend also gained proper multithreaded support to give a speed boost too. Useful for those where Vulkan doesn't quite work right just yet.

This release also comes with various other performance improvements and bug fixes. They mention Retroarch support like it's new, but looking around it seems that's been a thing for a while which is confusing.

Great to see another emulator pushing forward to keep a platform alive. I don't really do any emulation personally, but it's great for those that do.

However vulkan have issues

Various issues stay in 1.7.0 development for solved case resize windowed using vulkan

But in middle of this, them add opengl multithreading acccording devs this shows performance improvement

OpenGL backend now properly multithreaded, giving a
good speed boost.

In my case stay running good

I think the retroarch support was handled through an unofficial fork based on an ancient version previously. It seems to build from the official source directly now.

Nice. Haven't used it for years though. Might give it a shot

Anyone know whether the Flathub version is official?

I think this is even greater news on phones. Games are finally playable now on a low-end SnapDragon 400 phone, where on a mid-range SnapDragon 615 two-three years ago couldn't get a good framerate and so resulted in constant audio lag. (SD615 got close when I dropped it to 2x rendering res and heavy frameskip, but the audio was still crackly enough to keep me away).

These aren't vulkan enabled chipsets either, but it's likely due in no small part to the Opengl multithreading.

On the PC Side: (I'm on RX 560 with Mesa 17.2)
Vulkan seems to hold framerate slightly higher with the same settings enabled, OpenGL seems to drop harder when it does.
However, the buggy fullscreen/window resizing is a point of contention, and the audio slowdowns are not noticably better
