New limits for NWN 1

I often get frustrated with some of NWN limitations, like polycount, texture sizes, etc. In the old days, when NWN was created, 512x512 tga was considered huge, and dds conversion was required. Models tended to be low-poly and chunky. Nowadays, with majority of hardware (graphic cards, CPU) you can use 2048x2048 tga without too strong game "hiccup".

I wonder, what the new limits are. How high polycount would you reccomend for:

- tiles

- placeables

- creatures

And what about texture sizes? Is it good idea to use uncompressed 512x512 or compressed 2048x2048? What are your experiences with hogh-poly models and textures of size 1024x1024 and above?

Older games typically cannot make use of extra VRAM.  The amount of things that can be stored in the VRAM is going to provide the bottleneck.  Things slow down when the video card cannot render from its own memory and has juggling the cache.  And then some games are better than others at managing the cache- some just slow down, some just become susceptible to crashing (I feel that the latter is the case with NWN, but I don't have the expertise to definitively pinpoint that sort of thing.)

I have read elsewhere (I'll try to find the link if I can) that people have tested the "Max Memory Usage" setting in the configuration file (a setting added in th 1.69 patch if I recall), and could not find any improvement beyond a value of 128.  If that's the case, that pretty much sets the upper limit on the size of content NWN can use.

I think the problem you have is not so much the size or complexity of any particular resource.  The problem is trying to stuff multiple big resources into the cache at once.

O.K. Thanks. Back to low-poly and/or smaller TGA's then. The only improvement "to do" seems the quality of textures.

Actually, this has been discussed multiple times over the years.  You MUST remember that NWN1 was created to work in win95 and was expanded a bit to work with win98.  XP didn't really offer anything new for NWN.  Regardless, when NWN was created a 512meg vid card was the max you could find.  The multi-core processors are not truly used either, you can force nwn to use the 2nd or 3rd processor etc, but it will still only run on ONE cpu, regardless of the fact that you may have 8 cpus installed.  For CTP, when we were forcing as high as we could go, we never found ANY advantage to a 2048x2028 texture, 1024x1024 seemed to be the highest that the game could use.  Typically, 512x512 was truly all that was needed and having 1024x1024 was only providing a very minor improvement over the 512.  2048 never displayed at that level, regardless of what settings you attempted to use and thus just wasted bandwidth and disk space without really providing an improvement in game.

 

The game and toolset were created before higher graphics were even possible.  The engine was never upgraded to recognize the options of better graphics abilities and most definitely did not get upgraded to recognize the better vid cards.  It simply ignores stuff that it truly does not understand.
