Against my better judgement, I bought the remaster and tried it out. It's not terrible - some stuff like higher res textures do look quite a lot nicer and looks MUCH better in person than watching a Youtube video. However, the one thing I could not stand was that the performance was surprisingly shitty around the small towns/villages/cities. For example, the very first little settlement you run into (Gorhart) would drop my FPS to the upper 50s. By comparison, the original version is 120+. The visual difference doesn't even come close to accounting for such 50% or greater performance loss.
The game definitely needs patches. The performance is pretty poor, I've had a few crashes and visual bugs too (armour or weapon asset not loading after a save load). Nothing game breaking but disappointing for sure.
