In an ongoing programme to improve my PC I recently installed an Nvidia GTX 460 1GB GPU and when I intially tried to open TRS2009 I found that I could not move any trains. I had previously had it set to OpenGL but when I tried switching to DirectX suddenly everything worked!
At the same I noticed that Resource Cache Size is set to 32 but there's an option to set it to (I think) 1024.
So , a couple of questions 1) What actually determines whether you use DirectX or OpenGL? I know this may sound silly but I like to understand WHY I need to do something as well as whether I should do it.
2) Since I can set the Resource Cache Size, how do I know what size to set it to?
Thanks in advance.
