Applies to both - if someone originally designed the scene with a single light bulb source for example but then not getting the mood they wanted added some invisible point lights to bake in additional lighting detail you can't necessarily replicate that by stripping out the baked lighting and replacing the light bulb with RT/PT and you can't add additional invisible sources with real time lighting as it will just look odd, so you'd have to go back in and rebuild the environment around RT/PT to capture the same mood with maybe different light sources, etc. which is often limited by the modding tools/source availability - usually the original raw level data doesn't ship with modding tools and IP rights restrict reverse engineering for anything released to the public.
No spoilers please. Some people still haven't played this yet.As for the game as a whole, I think that HL2 has a stronger first half. It drops off a bit shortly after you get control of the ‘ant lions’.

I downloaded the demo, installed , when it loads up it says I need latest graphics card driver , I have a NVIDIA GeForce RTX 2070. Can anyone give me a download website.
Thanks David
