The quest for better emulation is never quite done, it seems. The open source PS2 emulator saw its first major stable release in years a few months ago and since then more exciting stuff has been under development.

If you’re not familiar with PCSX2, it’s one of the oldest PlayStation 2 emulators around. While not completely perfect, it’s allowed for reasonably good emulation of titles for a long time and has gotten noticeably better on Linux as of the last few years. Back in May, PCSX2 released its first new stable version in four years and, with it, brought countless improvements and fixes as well.

The development hasn’t slowed since and there’s plenty to love in a recent progress report. While there’s a fair bit of code refactoring and bug fixing, I’m mostly excited about some the accuracy improvements that have been implemented. Z-buffer improvements, for example, solve many text and HUD display issues while dithering support and blending improvements make things look more as they were originally intended.

I’ve got quite a few PS2 games from back in the day and, as PCSX2 has steadily improved, it’s been fun to revisit those titles. While things aren’t quite perfect yet, there’s an impressive amount of compatibility. Even software rendering is relatively manageable for those few picky titles that don’t play nice yet. Still, projects like these are invaluable for preservation of old games even as the original hardware becomes more difficult to find.

There are still quite a few milestones that PCSX2 has yet to reach but things are looking good. 64 bit support is in the works and even more accuracy improvements have been hinted to be in the pipeline. It’s unclear if and when the emulator will get a Vulkan renderer but with a macOS port in the works and the sorry state of OpenGL on that platform, it may well be that they implement a Metal compatibility layer atop of Vulkan.

You can give PCSX2 spin by getting it from your distro’s package manager or compiling from source.

History, sci-fi, technology, cooking, writing and playing games are things I enjoy very much. I'm always keen to try different genres of games and discover all the gems out there.

Oh and the name doesn't mean anything but coincidentally could be pronounced as "Buttery" which suits me just fine.

Vulkan is already implemented on Mac OS via Metal, using the layer that comes with the VulkanAPI installer.
At work, we run the same Vulkan code on both Windows and iOS, without issues.

Hi !

Anyone have this issue with RadeonSi driver with a navi card (RX5500XT) ?

I haven't seen any visual corruption in OpenGL games/apps with my RX 5700XT, if that helps. I'm using Kisak's Mesa packages as well.

Seeing as the 5500XT is a slightly more recent chip, maybe try upgrading your kernel? Plenty of Navi fixes have gone in since Linux 5.4. Mainline makes it easy to try Ubuntu's mainline kernels if Pop!_OS doesn't provide one.

I suspect that he was referring to the same layer that you are, MoltenVK. I think his point was that, though he doesn't have any information about when a Vulkan renderer would be released, it seems like the MacOS version would be more likely to rely on MoltenVK than any other approach, which would mean that the Vulkan renderer would have to be implemented as well for the MacOS version to be released (much more likely than a separate Metal renderer being developed).

There is also the Liquorix kernel available as another alternative. I'm not recommending one over the other, just giving another option.

The developers haven't outright said MoltenVK in any public post that I've seen, but it's a fair inference that they're looking at it for a solution. The impression I've gotten is that some developers may be playing around with Vulkan in their own spare time but it's not exactly a priority for the project.

The new kernel (5.7.11) don't help with artefacts in PCSX2, i'm going to upgrade MESA with Kisak PPA

So... same thing :(

Quoting: BTREYou can give PCSX2 spin by getting it from your distro’s package manager or compiling from source.

Or if your distro isn't up-to-date, you can take the easier route and get the latest version (v1.6.0) from flathub: https://flathub.org/apps/details/net.pcsx2.PCSX2
