Hi guys, I just have a simple question.... I have an iMac 2.8 Ghz with 2 GB of RAM. Now, it's odd because when I installed Leopard (by the way, I erased and installed), the usage of my RAM skyrocketed. A whole GB of RAM was used for just using the necessities and some other apps like my web browser and iTunes.... It ended up with me having about.... 90 MB of Free RAM, 1000 MB of inactive ram and the rest utilized for what I was doing... NUTS! When I had my Tiger, I had not experienced such a drainage of RAM like this before. I could run After Effects CS3, iTunes, and my browser with absolutely no question about the usage of RAM when I ran on Tiger. Is there a reason why? Also, my experience with Gaming has severely dumbed down. To play just Halo, a nearly 4 year old game, it requires me to play on very low resolution and graphics settings. Otherwise I get a lagging performance. I have a Radeon HD2600. Why am I experiencing this?
