My system specs are: AMD Ryzen 5600X, 32 GB DDR4 RAM, AMD Radeon RX 480 (8 GB) with the latest drivers, Windows 11 Pro 22H2 During the game (Version 1.64), I came across two bugs: The 1st one occurs in Chapter 2, Level 6, "Swamp" where you have to fight against the 2nd boss, the "Swamp Thing". Here, the game repeatedly crashed, giving an error message about /Data/Lscripts/Main/Game.lua. According to my Internet research, I found that in order to resolve this issue you have to invoke the Task Manager while the game is running but paused (key P). Use ALT+TAB then to return to the Desktop where you can open the Windows Task Manager (right-click on the "Start" symbol, then choose "Task Manager"). If the Task Manager only shows a few processes (which is the default view), click on "More details". In the table of processes, under "Name", find Painkiller.exe. Right click it and choose "Go to details" (or similar; I have a German Windows 11). When you are on "Details", right-click Painkiller.exe again and choose "CPU Affinity". A small window will open where you can choose the CPUs you want to use for the game. Uncheck all except for CPU #0, then click "OK". Then go back to the game and play on. The 2nd bug one comes right in the next level (C3L1), "Train Station". Here, it seems, that saving the game manually using either "QuickSave" (key F5) or via the "Load/Save" menu causes the game to become unstable. When reloading a QuickSave, or even an AutoSave, the game was likely to crash while loading. My solution was to play this level without saving right from the start of the level. The AutoSaves (those red glowing "campfires"), however, were safe to use. In the following level this problem did not occur. My problems may be related to my specific hardware. But if you find my review through a web search because you have the same issues you might have a way to resolve them now.
