Are these really that big of a deal? I've been doing some testing with some high polygone placeables (like 4000 for standard placeables) and 2048 x 2048 textures, and I haven't seen any issues with perfomance what so ever. The high res textures in particular look amazing yet I've heard the engine can't handle them, however this obviously doesn't seem to be the case.
Anyway, just curious if it really is that bad an idea to have the odd placeable with higher polygons and sweet lookin high res textures, as I'm not seein any issues on my end.
thnx!
High polys and high res textures.

I have made skydomes with textures above 2048, adn we have a few placeables on PWs that are above 20k

they will cause slow downs. the engine ain't programmed to render lots of polys in one scene. just use the city hak pak and load the test module and you will instantly notice. the gamebryo engine can handle this amount of tris easily while electron hicks up.
you can increase the performance with lods but in the end it's better to use lowres models for something that is often used in your area. of course there's no problem if you use a higher res for a prominent model.
textures are different league. dunno much about the engine in this regard but imo your graphics card determines how much memory will be used for textures. so if you have a 2gig card there's much room for lots of 2k textures before virtual memory will be used and frame drops will occure. in the end it's the same with polys. it's bad to replace everything with 2k textures and high res models

K thanks guys, pretty much what i figured. It is actually for more prominent singular models of an area rather then it being entirely populated with what I have planned. Just wanted to make sure there was nothing I was missing before I went and broke any cardinal rules of the nwn2 engine.
Thanks again for the info!

If you're designing for high-end single-player and have a modern graphics card, it doesn't matter. I'm not aware of any real 'engine' limits, only limits of the graphics cards the OC was speced out for circa 2005/6 when the game was developed. If you're designing for players of NWN2 (as opposed to players of Skyrim), it's best to stay within the prescribed limits and use LODs.
The other day I ran around a very complex 32x32 outdoor area on my laptop with an ATI HD5870 using a PC with a 20,000+-polygon and 2048x textured pre-decimated test haircut. I even tested the same set up on a circa 2008 laptop with a Nvdia Qaudro NVS 104M accesing the module as client running against a server, and saw no issues or performance impact.
That said, I've had users with particularly crappy video cards complain about being able to see collision spheres in our circa-2006 content, so YMMV.
