Many 32-bit Proton games are not working because they are running out of Video RAM (address space to be precise). More details in doitsujin/dxvk#1318 (and numbers in doitsujin/dxvk#1318 (comment)). Noting that D9VK shares the same limitations as DXVK.
There are many demanding 32-bit games on Steam that do no work because DXVK occupies more memory than native DirectX implementations and does not manage collection and defragmentation as well as its native counterparts.
Large Address Aware (LAA) flag does not always work (see #555 for anecdotal example) and LAA might just not be enough.
Proton is a big DXVK consumer and working on more advanced memory allocation mechanisms within DXVK would help with many Steam games.
