UPDATE - March 2:

　　During Microsoft's Xbox One/Windows 10 gaming showcase in San Francisco last week, Rise of the Tomb Raider was playable for the first time running on DirectX12 (DX12).

　　DirectX 12 Showcase: Rise of the Tomb Raider, Ashes of the Singularity, King of Wushu – Square Enix, Snail, and Stardock showcased their latest DirectX 12 enhancements for Rise of the Tomb Raider, King of Wushu, and Ashes of the Singularity on Origin PCs, iBUYPOWER Revolt 2, and Maingear PCs. Ashes of the Singularity is taking advantage the DirectX 12 multi-adapter technology, allowing PCs to use multiple GPUs, even from different manufacturers. Rise of the Tomb Raider was playable for the first time at the Xbox Spring Showcase running DirectX 12.

　　It looks like that Nixxes and Crystal Dynamics may be releasing a DX12 patch for Rise pretty soon.

　　ORIGINAL STORY:

　　Olek clarifies that he achieved his ‘edited’ launcher by replacing the original game executable.

　　"Monitor" launches the game and it stops working after the developer startup screen.

　　"Exclusive Fullscreen" opens the setup menu.

　　"Display" opens the official website page for the game.

　　"Graphics" opens the official Tomb Raider facebook page.

　　"Options" opens the official Tomb Raider youtube page.

　　"Stereoscopic 3D" opens the Square Enix support page.

　　"Enable DirectX 12" closes the launcher.

　　Since the 1.0 version of Rise of the Tomb Raider, DX12 files have been found within the game directory of the game, and it appears that Nixxes will eventually release a DX12 patch for the game.

　　Rise of the Tomb recently received a patch that includes several fixes and tweaks that vastly improve the game’s experience.
