It should be said though - and this is now partly the reason why we're working to release updated texture packages:
if you install any of the new textures in this thread's OP, your client will crash while zoning more often regardless of how good your computer is (explanation below). So if this is something you care about, I'd actually recommend not using any of them, and if you've already installed them I'd recommend reverting back to the original
high-resolution Trilogy textures.
That said, all textures such as those in the OP are going to be made available in a way that will not make the client crash. The reason this happens is because the Titanium client is a 32-bit application, and can therefore only use a maximum of 2 GB of your system's memory (actually only about 1.75 GB to be more precise). The way it stores data in memory is also really inefficient, which ends up leading to memory bloat issues when you zone between data-intensive zones - as soon as it gets anywhere near 2 GB of data stored in memory, it throws an exception and crashes to the desktop. So it doesn't matter if your machine has 2 GB or 16 GB of onboard RAM, or whether you have a SATA or SSD hard drive, the Titanium client will crash all the same once it hits that threshold.
And keep in mind that it's not just writing zone textures into memory but also NPC and character and armor and weapon and held item textures as well - everything that's visible, basically. So if you install the updated West Freeport textures you are going to crash when zoning into and out of West Freeport much more often.
We're solving this issue in the upcoming packages by doing tons of compression. To give you an idea of the difference this makes, the global_chr.s3d provided in the OP is about 167 MB, while the global_chr.s3d in the upcoming package which contains all of the same textures plus tons of newer and higher quality textures is only 13 MB.
So yeah, I don't mean to knock the work that Chebby and Nysus et al have done because it's exceptionally good, it just needs to be compressed down to a size that the client can handle.
