Guessing or do you have some edge case to present? Last I tried portal 2 ran fine on 64bit system. In fact I’m not entirely use I have ever actually ran it on 32bit one.
Guessing. To my limited understanding it relies on 32bit OpenGL drivers. Or later they made vulkan support, but that needs to be enabled via custom launch option “-vulkan”
