I'm not saying you're wrong but if you really look at the textures in games they aren't very pretty for for most part and what I feel need the most attention... to hell with all these goddamn lighting effects and DX10... make the textures look REAL for fricks sake. /rant

Now that I think about it, maybe that only serves to prove your point more as, compressed textures would theoretically look worse... similar to how compressed sound sounds worse.

Though I'm not sure where exactly you get the idea that BF doesn't have this.. (single DVD-ROM just like all the other games.) Then again, I am always in the map first in BF2142...
It was an example; the numbers are not exact - they vary from CPU to CPU, and game to game. The point, however, holds true.

Game developers would rather have a highly compressed format that takes longer to decompress into memory, than one that can simply be streamed into memory with minimal CPU usage.

Now obviously, it'd be crazy to use 32bpp bitmaps. That would be a total waste of space, shooting the texture size up 10x higher or more. 40GB on your HD, easily.

However, game devs don't have to take a bunch of JPG's, wrap them in a proprietary format that has some extra data, zip that, and then zip it again. It's just wrong, and it hits your CPU...

BF2142 just happens to be efficient enough at loading textures, that you will see a difference with RAID. I don't know where the overhead cutoff is, but to continue my example - BF2142 might be able to load 95MB/sec on your average stock-speed C2D. RAID will provide ~130MB/sec, much higher than your average ~65MB/sec, which provides a significant boost. That would drop the texture loading portion down to ~68% of what it was. The map loading portion won't drop much, as there's no way to make loading models and polygon data easier on the CPU. The only way to further drop it, is load non-conflicting data on separate CPU cores.

If you really want faster game load time, have drive 1 as your o/s, have the drive 2 as your games, go into computer management, go to disk management, add drive 2 as your d: and mount to folder c:\\games and where ever else your games are in. So now you have drive 1 as pagefile and drive 2 loading your games both at the same time with out slow down. I found that faster then a raid 0

I did raid0 for a long time...then I did raid5...back to raid0...when one of hard drives died I decided I'd better get a new drive and I just got one 250GB one to replace the two 80's I had in the raid0 with intensions to get another one to raid it. That's when I noticed no performance drop what so ever in all my real world uses...including the massive amounts of pdf files I use. And since I only really need about 50GB of hard drive...I've given up on the whole raid thing.

and all the hard drive I used have the same RPMs and cashe; they were all SATA 3.0's as well. If raid0 and raid5 gave any sort of performance increase it was so neglible that I can't tell.
