Portable GTA IV on PC

This method works for any older GFWL-based GTA IV  1.0.0.0 - 1.0.8.0. If you have later game version you should downgrade it first.

Portable GTA IV became possible due to XLivelessAddon settings and savegame folders redirection.

Red Dead Redemption 1 on PC using Xenia and keyboard+mouse

 

As of April 2021 Red Dead Redemption for Xbox 360 is playable on PC thanks to recent developments in Xenia emulator but default Xenia controls are far from perfect. This guide helps to configure X360 gamepad emulation (no physical gamepad required for playing) for PC RDR2-compatible keyboard and mouse controls.

ENB with DXVK for GTA IV

What GTA IV version to use for ENB

Version 1.0.4.0

·        Better performance, better look

·        CONS: on some GPUs/drivers may initialize graphics and load game very slowly, no FusionFix

Version 1.0.6.0+

·        Has more robust video initialization routine. May work better than 1.0.4.0 for some GPUs/drivers.

·        New shadows implementation, better look but GPU-demanding.

·        FusionFix v1.10 works

In general you may use any GTA IV version provided it is properly up/downgraded. The guide was successfully tested on:

·        GTA IV 2020 Complete Edition properly downgraded to 1.0.4.0 and 1.0.7.0

·        GTA IV Razor1911 original release upgraded to 1.0.4.0 and 1.0.7.0

Antialiasing with DXVK and GTA IV

This antialiasing method is very simple and uses older Sweetfx that is based on injectSMAA. 

• SweetFX antialiasing works for fairly modern GPUs e.g. very good at rx580, OK at gt730. 
• It is not CPU hungry and works without significant fps degradation even on 2-core Athlon X2. 

Latest Reshade may also be used for Vulkan antialiasing but it is harder to install/configure and at the moment it works only in global mode e.g. it will affect all games that output through Vulkan. 

How to play Red Dead Redemption 2 from offline

As of July 2021 this method works again. I successfully tested both LaunchRDR2.bat and desktop shortcut for PlayRDR2.exe on
- RGL 1.0.42.369
- RGSC 2.0.8.5 - after every RGL/RGSC update you should redo steps from "Required setup steps when connected"section
- RDR2 build 1436.25 (Blood Money/DLSS update)
- Epic Launcher 12.2.10-16850973
Be advised that although Rockstar is commited to supporting offline mode it may inadvertently break again in some future RGSC update. Offline mode launch with saved RGSC credentials used to work until Rockstar broke it in October 2020 RGL update, then after my ticket they fixed it in November 2020 RGL update. At least now there is "alternative offline running method" by EMPRESS V2 & Mr Goldberg.

This method works if you legitimately bought the game from Epic Games Store and want to play through RDR2 story mode offline. The method (after  modifications for specific store) and Troubleshooting section are also applicable to RGL and Steam RDR2 versions.

TL;DR - recent Epic Game Launcher and Rockstar Game Launcher versions explicitly support offline mode and RDR2 story mode can now be started without internet connection using only saved RGL/RGSC credentials. Moreover, it can be started from custom desktop shortcut for RGL without running Epic at all as long as this shortcut has correct saved Epic credentials as parameters - they can be obtained from RGL logfile.
