Is this a typical time to compile maps ?
Every one is different, so there's not really a typical time. Does very much depend on the spec of your computer too. I noticed when I got an Athlon XP over the Duron I had I got a big increase in the time it took to do the lighting and VIS, because of the extensions this had.
There are quite a few options that you play around with if you want to try and decrease the time it takes. Look in the ZHLTReference.html file for all the switches you can use.
Is there a way to compile with all lighting disabled (but with normal 'daylight' like it does before you start adding lights ?)
- so I can test structures/layouts, etc without having to wait ages ?
Just don't inculde RAD when you compile. Think it's just a tickbox in Hammer, but really if compiles are running slowly, you would be better using batch files as this would let you close Hammer down and free up the memory which this uses to devote to compiling.
The r_speeds on the map currently range from 60 to about 850 according to where you are - is this OK ? Think I heard somewhere that you should aim to keep them below 800.
It's hard to tell when you start, as you if you do a basic compile with HLCSG and HLBSP, the engine is still having to render the whole map when you run it. It's not until you do a full VIS that you can get a true impression on how well it's gonna run.
Figures in the 1-3000s can be okay at the stage you're at. Best thing you can do is just build it as neatly and simply as possible, then do a full VIS and see what speeds you getting, then think where you can make improvements (or if you're lucky add extra bits).
Acceptable values for finished ones. In the past in was suggested 300-800, but it's probably okay to go up to about 1000 today on most peoples computers. Also depends on the areas themselves - a central area which is gonna see a lot a action should ideally be kept as low as possible, while spawn areas which are only used once are not as important.
It's worthwhile running round some of the official maps with r_speeds on and seeing what they are like. Just don't run round sanjuan like that.
