Bug ID: 58542
           Summary: Dual GPU 32-Bit PhysX
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Batman Arkham Asylum v1.1
32-Bit PhysX has 3 modes:
OFF, Normal, High.

Normal & Off work ok.
PhysX works, but Not High "Dual GPU",

Windows driver allows to force PhysX to a single GPU, Dual GPU or CPU.
Linux driver 470 does Not.

Problem #1. instead of using Dual GPU on Linux or a single GPU,
PhysX falls back to CPU PhysX in Linux.

Problem #2. CPUs are very slow for 32-Bit,
Batman Arkham Asylum PhysX High, requires 1-core 100% CPU load,
gives 15fps on modern CPU´s.

Problem #3.
Nvidia deleted 32-Bit PhysX support in hardware since 2016-Q4,
IF you install a 2017 GPU like P1000, in Windows, Activate/Force PhysX GPU,
Does Not work.
Only work with 2016-Q2 & older GPUs.

im confused where could be the problem...
Linux Nvidia 470 driver?
Wine?
winetricks?

¿how does Wine handle 32-Bit PhysX requests?
block diagram? signal path?

I'm beginning to think this isn't helpful as a matter of policy, because it
sure isn't helpful here.
