Memory Usage
 
Hi All,

Im trying to find out why Enemy Territory runs so bad in outdoor areas of the game (20fps, indoors 90fps). Quake 4 and Doom 3 both run fine on my machine.

Anyways, i was looking at my memory usage, and noticed there is only 40MB of free memory when nothing but the system is in use. This goes opposite to my Windows knowledge where there is always memory available. Is there something im missing

you (presumably) paid good money for the memory sticks in your pc right? would you rather that the operating system completely ignored the space and waste that money, or would you rather that it saved old memory that it believes may be needed agani in order to improve performance of the system? i'd rather have the latter personally. That cached value is the old memory that, should more memory be needed for current processes that the older caches are removed.

And if that was a little too acidic (sorry ... :p), try this

One of the most useful things I have ever heard regarding memory:

"Free RAM is wasted RAM"

Linux is designed to use all your memory first as others have stated. I went out and bought 2 1gb dimm modules. System runs way better and memory is relatively cheap these days.

I noticed you have sendmail, ssh, http, samba and kde running... :p Personally, I'd kill all of that and run with fluxbox for ET... Atleast kill your network servers while your playing online games.
Know that doesn't help you too much but it's something to try anyway. I always got somewhat jerky performance with ET on Linux. Haven't tried it yet since I got a 6200 and more ram.

I have a 'Games' option on my grub bootloader and we all know what that is... Hmm... Kinda in the mood for ET now... Need a medic!!! :D
