Summary: GTA2 runs really slow with RenderTargetLockMode
                    readtex with a GeForce FX 5500
           Product: Wine
           Version: 1.1.30
          Platform: PC

        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

When trying to play GTA2 in newer Wine versions with a GeForce FX 5500, the
game will run extremely slow because RenderTargetLockMode readtex is now the
default. Switching back to RenderTargetLockMode readdraw allows the game to
work correctly.

When setting RenderTargetLockMode disabled, the intro movie doesn't display
anymore, but ingame will work extremely fast. The performance is really good
then.

It appears there is currently a significant performance problem with GeForce FX
5500 cards and RenderTargetLockMode readtex. Details about my system:
AMD Athlon 1GHz
512MB RAM
GeForce FX 5500 with 128MB
Ubuntu Hardy
Driver version: 173.14.16 (the latest that supports my hardware as far as I'm
aware)
