A user from the Sanadsk channel demonstrated how easy it is to create remasters. He took the PS2 version of God of War 2, launched the game on PC, having previously raised the resolution to 4K and installed ReShade.
The result is a fairly high-quality result.
Approximately such remasters release studios, but they ask money for it, although there is nothing difficult about it. Sanadsk even using ReShade with Pascal’s RayTraced Global Illumination shader simulated the effect of global illumination in real time.
In addition to God of War 2, the enthusiast’s channel has Prince of Persia: Sands of Time and Legacy of Kain. The latter looks especially good with higher texture resolution.
