Recent (25.3.1) Radeon drivers for Windows break LBP1 on Vulkan with MSAA on 5700XT - Hadamard Gates - 04-06-2025
Hello. My GPU is an 5700XT. Starting with the Radeon driver 25.3.1 for Windows released on the sixth of March 2025 (so merely a month old at the time I'm writing this, it's in fact the current "recommended" driver (I don't recommend it)) Littlebigplanet [BCES00141] is broken graphics-wise with MSAA antialiasing enabled (see attached pictures). With MSAA disabled it's also, though to a lesser extent, broken in a different way (glass, including the Pod side windows, as well as score bubbles don't look correct), so naturally I seeked to get AA to work, which I knew it could because it did before I updated my drivers. So I do suspect it's merely a driver bug, but as this emulator is the only use case scenario where I noticed it I am posting it here, also to let others know. I know that these GPUs had a hard time with antialiasing in the emulator, but the issue was as far as I can tell fixed. I don't know if it's that same issue, but if it is, then with new drivers it became unfixed. Default settings were applied in the driver, although I tried tweaking some of them as well, to no avail. Using OpenGL the issue is not present, but as ever the performance is subpar compared to Vulkan.
System: RPCS3 v0.0.36-17745-613212f9 Alpha | master. ASUS STRIX 5700XT, AMD 3700X, B550 chipset, 16 GB RAM. Windows 11 Pro 24H2 build 26100.3476.
Last working Radeon driver: 25.2.1. First non-working Radeon driver: 25.3.1.
Last working Vulkan driver: 2.0.317. First non-working Vulkan driver: 2.0.331.
The driver 25.3.2 does not work correctly either, I checked.
