I am about ready to buy the US Terrain Mesh for FSX. I see that FS Genesis has a download version and a DVD version. The DVD version is supposed to have better vertical resolution (.25) as compared to the download version (.50). I assume that means .25 meter vs .50 meter. Will this be all that noticeable?

 

I assume that the extra $20 that I would have to spend for the DVD version might be best spent elsewhere? Any thoughts would be welcomed.

Unless you're an insect, I doubt you'll see the difference. I just bought the download version myself, though I can't comment on it yet as I still need to install it.

I think it would be hard to find anybody who owns both versions. I bought FSGenesis US Terrain Mesh for FSX (10m) in DL version and I'm very happy with it. This mesh really improved apperance of terrain especially in connection with photoscenery. If you don't be flying extremally low you won't notice difference between vertical resolution 0.50 and 0.25.

I decided to buy 0.50 version because of smaller data size which has influence on performance while flying and loading new data for next terrain tiles. Maybe it isn't too significant factor in overall performance but high resolution mesh adds much more data for processing scene than default FSX mesh so I chose more performance friendly version.
