Yes some of the maps are quite small. Most notably the JP Chaos Theory Nublar map and the JP3 Isla Sorna Site B map. The maps look great. They are just too small. None of the maps are as big as people hoped or were led to believe.

I am currently playing the JP Chaos Theory scenario and I can see the map for myself now and it is small. Though I think Frontier considers it a large map. It's clearly not. It's more like a medium or something if even that. The JW Chaos Theory map looks slightly larger than Nublar 93 from the JWE RTJP DLC. JW got a better map it seems. None of the maps in the game are really big.
I saw a post over on the subreddit that said mods can easily be ported over to JWE2. There was a mod that got rid of the map boundaries so hopefully that mod can be ported over to JWE2 easily. Cause it looks like it will needed.
My system specs are in my signature below and even with my hardware while playing I am seeing frame rate drops and this game makes my GPU get a bit noisy. This is at 1080p with all settings as high as they can go. Not 1440p or 4K, Just 1080p. So I can imagine what this game is doing to consoles with their obsolete APU's.
I am guessing with the new dynamic AI and animations we got stuck with small maps again because of consoles. All that AI and dynamic animation will put eat up a lot of CPU processing power. Consoles use APU's. They don't have discrete GPU's like a desktop. That means the CPU handles the physics, AI and graphics in consoles. I have already seen people with Xbox Series X consoles saying they are experiencing performance issues.
But like I said even my with my hardware I am seeing a drop in frame rate. This game needs some more optimization work I imagine or maybe the engine does. It's not a big deal cause it's not a game that requires a high smooth frame rate, but being able to keep a steady frame rate it nice, at least 60 fps. I have seen my frame rate go below 60. I am not sure how far but I have felt it and seen it. I know when my frame rate goes too far below 60. 55 isn't too noticeable. But when you get below that you can see it and feel it in the gameplay.
