Grand Theft Auto V

What works

Single Player + around 50% of mods that I've tried. Things like cars, weapons, trainers etc. generally work fine.

What does not

Social Club and the components that depend on it*.

Some mods (possibly ones that depend on social club in some way). FiveM & GTA Co-Op for example.

Multiple monitors at different resolutions**.

Workarounds

DXVK is required with a 64bit prefix.

*I had to find a patch/crack that bypassed social club. This breaks
the multiplayer but the single player works fine. Some of the
alternative multiplayers mods may work, I only tested the two I
mentioned and I was unable to get them to work.

**I've got two portrait monitors and one centre landscape monitor. If
I'm using xorg, the game will always open on the left monitor if set to
full screen. If using wayland, it'll always open on the right monitor.
This happens regradless of the settings in-game and what $DISPLAY (or
$WAYLAND_DISPLAY) is set to. My partner's PC has two landscape monitors
at the same resolution and she doesn't have this issue. I've written a
launch script that disables my auxiliary monitors before launching the
game.

What was not tested

GTA Online due to social club being disabled.

Additional Comments

Tested on three systems:

SYSTEM 1 (Silver):

GPU: Vega 64 | AMDGPU

Monitor 1: 1080x1920 (left) 

Monitor 2: 3840x2160 (primary/centre)

Monitor 3: 1080x1920 (right)

Portrait monitors have to be disabled.

SYSTEM 2 (Silver/Gold):

GPU: GTX 980 | Nvidia Proprietary

Monitor 1: 1920x1080 (left)

Monitor 2: 1920x1080 (primary/right)

No issues other than social club.

SYSTEM 3 (Silver/Gold):
GPU: GTX 760 | Nvidia Proprietary

Monitor 1: 1920x1080 (primary)

Framerate average of ~30fps with lowest settings at native resolution and DX11. Interestingly, setting DX10 or DX10.1 results in a slight decrease in performance (3-5pfs).
