Severe Graphics Quality Regression in PoE2 (Previously Working Fine)

=== Path of Exile 2 - Bug Report ===
Date: 2025-06-01

=== System Info ===
Laptop: ASUS TUF Gaming A15 (FA506NF-HN004)
GPU 1: NVIDIA GeForce RTX 2050 (Driver: 32.0.15.7652, VRAM: 4 GB)
GPU 2: AMD Radeon (Integrated)
OS: Windows 11 (clean install recently)
Game platform: Steam

=== Description of the Issue ===
For the past 2–3 days, the graphics quality in Path of Exile 2 has dropped significantly and is now unplayable. The problem began suddenly without any hardware or software changes.

After that, I reinstalled Windows entirely, manually installed the latest GPU drivers from NVIDIA and AMD, updated Steam, and reinstalled the game.

However, since then:
- The graphics remain extremely blurry and low-resolution
- Many textures, effects and mob animations load late or not at all
- Settings in the in-game Graphics menu are locked (e.g. Texture Quality stuck on Medium)
- Changing from Vulkan to DX11 or DX12 has no effect
- Creating or editing the `production_Config.ini` file does not apply changes
- Forcing launch options like `--rendererType DX11` or `--noasync` has no real improvement

The game correctly uses the RTX 2050 card, confirmed via GPU monitoring tools. GPU load and temp are normal (85–88°C, 1.7–2.2 GB VRAM usage during play).

I had absolutely no issues prior to this — everything was running fine on High settings until a few days ago.

Please assist, as the game is currently not playable.

Thank you!
