This guide will help you configure your game and also updates and other improvements.

• reshader for Doom The Dark Ages
• you need to update the game upscaler to FSR 3.1.4 or use a newer or older version of DLSS dlss-swapper
  

🎯 Goal:Preset "Quality + Performance" – for those who want high FPS while maintaining great visuals (ideal for 1080p and 1440p)
Preset "Visual Quality Only" – for users with 8 GB of VRAM, prioritizing beautiful graphics without stuttering.
🔍 Understanding:This limit controls how much VRAM will be reserved exclusively for textures.
In the screenshot, current usage is 8809 MiB / 14076 MiB, meaning ~62% of VRAM is already in use.
For those with 8 GB of VRAM, capping this value is essential to avoid FPS drops, stuttering, and crashes.

I added another option to help with optimization and help you create a preset for your PC.
You can use the PC optimized version to further improve the fps

I left two options to help with optimization, I know the game is well optimized but if I can make it better, that's fine.
