SoF and S3TC
Got the relevant info from S3 (the power of plan files!) and incorporated S3TC into SoF. This means that all of the textures are resident on the card with no visible loss of image quality - this removes the bottleneck of uploading textures to the card and means the main memory copies of the textures are never accessed and paged out to the VM file, leaving us more memory for other things. Alternatively, you can just use higher res textures
