I used to have to avoid the full VLN layout as it would turn into a slide show on my old rig with 8GB RAM and the basic Quadro 2000 card. I found some more RAM and boosted it up to 16GB. I can now run VLN with 40 mixed class cars at an acceptable frame rate. Now to see if I can stuff a decent graphics card in the limited space of the Dell T1500. Needs to be shorter than 220mm, so I may be limited to a 1050ti, but that's better than what I have.
