PLEASE NOTE: 

Changes to the track [AAIOM] 3do do not change the driving surface or characteristics in any way.

Do NOT even attempt to use these files if you have previously determined that you need to run the LITE versions of this track. The track will not run properly on your system with either of these two files.


PURPOSE AND USE

There are two separate AAIOM.3do files and some support files in separate folders. 



Version 1.1 ORIGINAL FULL AAIOM.3DO

This is a copy of the normal track download FULL 1.1 build; optimised Draw Distance AAIOM [Track] 3do. This was designed to maximise frame rates and minimise CTD's [ Crashes to desktop ] issues for normal systems, especially when racing other cars; i.e. it is suitable for reasonably powerful PC's built in the last 4 to 5 years using Windows 7 - 10 and with significant amouts of Video ram and system Ram by modern standards. It focuses on minimal pop ups in forward camera views, but restricts rear views somewhat, e.g, views that are not seen in TV1 cameras. 

This is included to make it easy to revert to the normal Draw Distances if the Long Draw Distance version causes issues on your system.



Version 1.1 Long Draw Distance AAIOM [Track] 3DO

This version of the 1.1 build improves in a very minor way, a couple of forward views, but is primarily aimed at restoring the long rear facing draw distances included in the first release 1.0 version of the track 3DO, which caused quite a few frame rate hits and crashes on many systems. This includes all 1.1 enhancements.

What it does is eliminate any screnry drop outs in mirrors or when using rear facing cameras watching replays. It also improves the long distance views from a very few TV1 cameras; e.g. the view to the rear at St Ninians where you now see the grandstand and at Quarter Bridge back up to the very top of the hill.

This track 3DO might also assist anyone making movies on the track with CCM.

The downside of this Long Draw Distance version is that it is only suitable for very high powered PC's and even then, could cause issues, including screen freezes, stuttering, frame rate drops or a CTD [ Crash to desktop ] , especially when using the more graphically complex Mod cars and / or when racing other cars, A.I. or on line.

Use at your own risk!

I have included all the post Version 1.1 small updates, also published separately for users of the normal FULL and LITE versions, up to and including changes made week ended 11th July 2019. These additional graphics files are essential to correctly display several objects when seen facing the rear. 

There are no changes to the track / driving surface or layout.

To go back to the standard Version 1.1 AAIOM.3do, copy / paste the "AAIOM Folder" from within the "ORIGINAL optimised Draw Distance Track 1.1 Version 3DO" Folder..into your C:/SIERRA/gpl/tracks... Folder. Allow that AAIOM folder to overwrite the existing AAIOM Folder in your.... /tracks Folder.

CARE: Do not try to copy individual files OR copy these folders into the existing AAIOM folder. If you do that the files wont work!
