### Quick summary The game starts and runs perfectly at full speed (60 FPS), but after a random amount of gameplay (usually between a few and several dozen minutes), performance suddenly drops to approximately 0.2-0.25 FPS. The game becomes almost completely unplayable. Restarting the game restores normal performance until the issue happens again. <img width="1920" height="1037" alt="Image" src="https://github.com/user-attachments/assets/3f18bb04-6a12-4b94-a40a-8deaf8aebb60" /> ### Details _No response_ ### Attach a log file [RPCS3.log.gz](https://github.com/user-attachments/files/29946254/RPCS3.log.gz) ### Attach capture files for visual issues _No response_ ### System configuration RPCS3 version: 0.0.41-19564 Operating system: Windows 10 x64 CPU: Intel Core i7-4790K GPU: AMD Radeon RX 480 4GB GPU driver: AMD Adrenalin 25.5.1 Renderer: Vulkan Title: The Penguins of Madagascar: Dr. Blowhole Returns - Again! Serial: BLES01219 ### Other details Expected result The game should continue running at full speed. Actual result The game suddenly drops to approximately 0.2 FPS. Sometimes audio briefly pauses but then continues normally. The game never recovers until it is restarted. GPU utilization drops to around 1-2%. Things I already tested Latest RPCS3 build - Deleted shader cache - Default settings - OpenGL renderer (game crashes instead) - Latest AMD driver (25.5.1) - Windows power settings - Different fullscreen/window modes Important observation Exactly the same hardware running Fedora Linux does NOT have this problem. The same game runs correctly for long periods under Fedora using Vulkan. Only Windows is affected.
