About the 3D graphic of new JT Napoleonic Battles games

[Raymod1986]

Hi, I'm an old HPS Napoleonic Battles (NB) series player, and I'm thinking of buying the newly release NB games John Tiller Software(JT) as some new games(such as Campaign Eylau-Friedland and Republican Bayonets on the Rhine) are only released on JT. 

But when I click into the product page, I find out that in the preview screenshot, the 3D units are shockingly ugly and small (or ugly because of too small) compare to old NB games released on HPS. 

Here's the comparison:

the clear and nice 3D unit graphic from preview image of HPS Austerlitz:


the small and ugly 3D unit graphic from preview image of JT Marengo:


Can someone tell me what's going on with JT's new NB games? Are the 3D unit graphic actually look like this in the new NB games? Is there an in game option allow me turn into the old HPS style graphic? And the last question, will the 3D units turn into this in my old HPS NB game (like Ausertlitz) if I use the update patch on JT website?
