John: How much of an improvement is TS2012 over 2010. I have seen and compared the trees with other tree versions (Trunda) and I must say the trees aren't all that impressive. Is there a major leap in graphics beyind the trees, or is it pretty much the same as 2010?
There is definitely an improvement in the graphics. The draw distance is longer and it's faster even in driver. The color seems more vivid, textures are less washed out than in the older versions. Overall for some reason the older versions of Trainz had blah texturing - pretty much phong like, and the flipboard trees, while current technology in 2000, really needed to go because they were a performance hog.
Personally I had given up on the old alpha-blended trees long before Auran had done officially, and was hoping years ago that they would go away anyway because they never looked good. I was constantly looking for trees from different makers, and had to finally settle on only a few that performed well and looked nice. This is a hard combination to work with.
Anyway when the Treez pack came out for TS2009, I ditched the alpha-blended constructions for them, although they were somewhat out of scale in some cases. Today I use both the Treez trees and the Speed Trees as well as third-party Speed Trees.
Now most people snicker and complain about the ST, but given that
most people today complain about everything, it's only natural. The advantage to the Speed Trees is that the program uses the GPU to render instead of relying on the CPU to draw the trees. This gives the CPU more time to concentrate on AI functions and program running rather than needing to do a task that can now be done in the GPU, which in many cases is just as fast as the CPU and has also a lot more pipes than a CPU does internally. Many people complain about the performance with these, but honestly I see better performance than I had with the old alpha-blended creations. There is also one thing to remember too. With SpeedTreez, you can get nice coverage with fewer of them, and not notice the difference. The thing is, you need to choose the trees that are close to the ones you have in your area. I use maples, oaks, birches, their English Tree, which looks like popular, and conifer variants.
When I go back and run programs, such as Operation Flashpoint, or MSTS I cringe when I see the foliage. This is the same technology that was used in Trainz until TS2010 came out. You can see the alpha channel outline the branches of the trees no matter how much the developer tried to hide it.
When I get a chance, I will post some screenshots of my work-in-progress update to GFisher's (George Fisher's) Gloucester Terminal Railway, whch I've electrified with trolley lines for passenger service.
