Geometry question.

It doesn't matter too much, but try to avoid it as it will split up your other brushes where intersections occur.

At least it will need more time when compiling.

Other phenomena unguaranteed.

You run into possibilities of extra unneeded faces which then get world rendered and lightmapped.

Try not to, but if it's a massive rework don't bother, my source maps where never that clean and they ran fine, source is running at like 200 fps for most people these days, a few faces here and there isn't going to kill it.

Who are these people? :o I barely manage to run official maps at 60fps and my computer isn't that shitty :o

@Sirlock it is a good idea to avoid brushes overlapping, it saves a huge amount of compiling time and it makes debugging a map much simpler (trust me, I've been there..). Also, cleaning it up can make you have some good ideas for the area , since you have to think the area differently

Well, when on occasion you see a source game in a hardware review it's hitting off the charts - any half decent gfx card in the last 2-3 years will be capping out at insane frame rates, I don't want to be harsh but a PC that runs source at less than 60 fps isn't anything to write home about Not saying you need a better pc, at the end of the day 60fps is perfect But not all games run on source engine. My point is that Source engine is very optimized and efficient, so unless your going crazy with your level or just have no idea what you doing it has quite a lot of breathing room in terms of performance.
