Virtualtex taking too LONG

[rl90599]

Hello, whenever I use virtualtex on a 32768x16384 texture map, it actually takes MORE than a hour to create the tiles.

Anyway, here are my specs:
Windows 10, running virtualtex on Cygwin, Version 10.0.17134 Build 17134
4 GB of RAM
27.8 GB of disk space (I had to run virtualtex on my "8 GB" USB, since ImageMagick creates a file at least 1 GB for no reason)
AMD E2-7110 APU with AMD Radeon R2 Graphics, 1800 Mhz, 4 Core(s), 4 Logical Processor(s)

After waiting hours and HOURS counting the files in ImageMagick's temporary directory until it reaches 513 (number of tiles + 1 GB file), it finally outputted the 512 tiles and deleted that 1 GB file. I still don't know why it takes more than a hour for me. Maybe it's either my 4 GB RAM or my USB, which uses FAT32?

All of the items you mention combine to cause problems. The in-memory image that's being cut up is at least 1.5 GB. (32Kx16Kx3 bytes/pixel) plus the sizes of internal scratch files and input and output files. The 1GB file is caused by ImageMagick not having access to enough ram, so it creates a "scratch" file. Using disk instead of ram is very, very slow. External, inexpensive USB disks also are *very* slow. If you haven't already, you should consider replacing your system's hard drive by a (larger, faster) solid state disk. SSDs can be more tban 4x as fast as hard drives.

Well at least I have a hard drive that is more than 27 GB of space, but unfortunately it got hidden where I could never find it. It also had many games installed there.

Thanks! I thought it was created there for no reason.

Welp, I guess the only solution to this is just waste my time waiting for hours and hours and counting the files until virtualtex finishes.

Windows 10, running virtualtex on Cygwin, Version 10.0.17134 Build 17134

so you are running a linux build through CygWin


THAT RIGHT THERE WILL CAUSE ALL YOUR ISSUES
