The envy has a variety of CPUs and some have a built in nVidia GPU so which does yours have?
If you get desperate

Cheerio John
Thanks John,
I unfortunately don't have the NVidia, I have Intel HD 5500 and it Chokes with Trainz, but I have learned to live with it for now.....Originally Ram at 12, I went to 16 Megs, max it will support for HP Envy model I bought from Costco it's almost 2 yrs old, I didn't realize it till I thought about it.
The 1TB drive was 4200 RPM, which is terrible for write speed with Trainz, but normal for Laptop to conserve your battery time!
Installed a Samson SSD, 1TB, thinking I could better if I did the Drive and Ram, and it did help, but the GPU is absolutely the most critical item as I see it, since you get hurt with Video Performance depending on Field Draw length, number of Trees and or Trainz items.....So that is where I choke, so I've learned to weed out excess Trees, and whatever else, shut off internet, close all but the programs I really need running, and that helps.
I use Carbonite, and have tuned it lower, so it takes longer priority wise to catch up on my files, but helps my Trainz performance.
With the Intel 5500 GPU built in on the board, your sharing resources with the mother board, great if your not a Gamer or playing with a Sim like this one or any other Sim Game for that fact. So I played with with my settings and below is what I'm running for now, if you see something not correct I open for changing the settings to try.......
I get a moderated amount of Frame Stutter depending on what density I pass thru on the Route.....I use WIN10, and Game Mode.......So far that has been stable no issues that I see. T:ANE with SP-2.
