Just out of curiosity, I opened the scene.dat file in VIM and it looked like this:
Don't know if it's just me but that looks like mumbo jumbo and I wouldn't know where to start if I was going to try and tweek the reflections or something!?
Also, I tried changing Glare LoD settings in the cfg file but that had no obvious effect at all. My sum total programming experience with games comes from creating ships for the space trading game Oolite. I recall having to hold down the shift key on loading the game for it to call up any changes I had made to the various cfg or model files. I think that cleared a cache and loaded the new files. Should I be doing that with SH3 if I tweek a config file? Anvart, you said cleanse the folder...is that what you mean? Clear the cfg cache (?) and if so how do I do that?
By the way, Direct X10.1 is listed in the Intel HD graphic and media control panel Direct X version. I have updated Direct X with various game installations so I had previously had Direct X 9. I've no idea wether SH3 is using 10 or 9? I just assumed it would use the correct version.
Once again, thanks for the help.
