The memory footprint increases as the game allocates memory to the different activities in the game and is not just related to the cache files. You seem to be doing everything you can to give you better performance on your machine so it seems that you are just limited by your machine specs. I notice that the minimum spec for Runescape HD is supposedly 1.5GHz processor.

Zhong, sorry I was a bit stupid before, and got the wrong end of the stick. Now I understand which files you mean. I have been using a computer with better specs than that which freezes quite often when running across the map especially on HD. I think you are going to have trouble anyway. I ran Process Monitor (from sysinternals) and that shows that the problems occur when reading the main_file_cache.dat2 file. That seems to be loaded into memory and never gets closed again which means that all the problems that occur are related to RAM and/or CPU speed. That means a RAM disk would not help anyway. Basically, follow Dark_Aura's advice and add more RAM as a cheap option.

That sounds unusual. The way they should be accessing the code in those cache files is to load them in when you start the game. I would think it is something else causing the problem. Would you say your computer is a decent spec? i.e. does it have a dedicated graphics card? Also, does the problem occur all over Runescape consistently? The reason I ask this is that on my new computer I had serious unplayable lag issues which I eventually worked out was related to the music in different areas of Runescape! When I muted it, I had no problems. It eventually cleared up and may have been fixed by a patch to Runescape or my sound card (can't remember which). There are some seriously strange issues that can cause problems like this. Try experimenting to see if you can work out when it happens. Oh and it goes without saying to follow the Jagex advice first if you haven't already.

Joe, everything you have said is perfectly correct except that what Zhong was referring to is the little used concept of a RAM disk which can be created manually through Windows control panel (somewhere). It is a way of treating a portion of the RAM as if it were another hard disk for faster access, a bit like a solid state drive I suppose. Anyway, in answer to Zhong, even if they allowed you to change the location of the cache, it wouldn't help as the dlls in there are loaded into RAM anyway and stay there for the duration of your game. They are used for the 3D graphics.

It looks like this is an oversight in the game. The fact that you didn't unblock during the quest now seems to suggest that you can't unblock it now. Obviously, you should be able to. I am surprised that it has not happened to anyone else. Lots of people do quests in a different way to how Jagex expects so you would have thought they would have spotted this. I would definitely submit a bug report for this. Edit: I couldn't really understand this but it looks like the same problem: Quick find code: 18-19-293-58434135 Edit2: Ah this thread might be more helpful: Quick find code: 18-19-153-58261757 :)

It means that your integrated Intel graphics card is unable to perform anti-aliasing. As far as I know, that is the case with all of these Intel GMA cards. The anti-aliasing basically smooths out the graphics and takes off the hard edges. Unfortunately, you will probably find it impossible to get a dedicated card for that machine.
