Yes, it happens. And it gets fixed. I see absolutely no problem with this. As for the refreshing, what's your specs? Keep in mind how much it's rendering too?
If they broke Counterstrike for more than 5 seconds can you imagine the chaos?
My system is more than good enough to run source, doom3, whatever you throw at it. Hammer reloads all its resources every time you restore the window from minimised, it allows you to change content without reloading hammer but the delay is rather annoying.
How can anyone not like Source mapping over HL1? I thought that when I saw how props, static, detailed, etc and all the other new things added were so much different then 3.4. If you give it time, you will come to find that EVERY aspect of source mapping is easier and greater than 3.4. Living in the past is kind of dumb....... I agree that the nostalgic feeling of HL1 is nice, but seriously get with the times!
I mapped for 5 years, its hard to shake that much experience on a whim, obviously with time I will. Yes its fun having all the new bells and whistles, though quite a few ive found so far need some considerable prodding to do half of what you want. Still, thats all the fun of spending another 5 years to become as proficient again!
Im not really going anywhere with this, just don't say I have a bad system as people say it so often its cliche or say that i'm 'living in the past!' when i'm posting my thoughts on the first few days with source after 5 years with 'goldsource' (rubbish name)
