RaceRoom Racing Experience displays a message that it cannot create Dx9 device due to an invalid call, and quits.

logos128 commented 4 days ago

The exact dialog message is "Failed to create Dx9 device: Invalid call." The game has two modes - the default d3d9 mode ("Play RaceRoom"), and a dxvk mode ("Play RaceRoom with DXVK"). The dxvk mode was added recently for better and smoother performance on Windows. The dxvk version used is 2.4.

The aforementioned problem occurs only in d3d9 mode, while the game runs correctly in dxvk mode. Obviously in Wine/Proton the d3d9 mode links against the dxvk dlls on system level, and in dxvk mode it links against the ones distributed by the game (in "x64dxvk" folder). So I did some regression testing and found that commit a7c2eb140e1eccaf9e9dce427549f2a985ea0d9d is causing the issue.

Thank you very much for the issue. I've gone ahead and made a apitrace that reproduces the problem https://drive.proton.me/urls/1BN9GZ3Q8M#LYU4inYSwNQW

Thank you for the report. The game is trying to create a device with 4 back buffers, 3 being the limit usually enforced by d3d9 at least in its hay days. I will drop the validation which should make the game work fine again.

P.S.: @Blisto91 just mentioned this is a 9Ex game, so it's probably something I overlooked since there are literally no 9Ex tests to speak of. With some minor tweaks it should be fixed soon.
