Only if you do it on a very large scale but your talking months of optimization work by quite a few dedicated people who know exactly what they where doing, which right now I'm the only person in the team who can truly optimize all areas of a staticobject and have far too much work on to think about this sort of thing :p

noob question, would this treatment also apply to kit geometries?

the lightmapping part no :p

decent LODs, LOD distances and cull distances, defiantly yes and something I've said in the dev forums for ages needs to be looked into :p

I noticed with the 128 player server I began to get reduced frame-rate when a lot of friendlies were around, so I'm guessing this was probably a big contributing factor.

That and the handheld weapons as some 3p models for weapons have the same poly count as a MBT, on arrearage the same as an APC so having a squad of 6 guys around you is like having 6 APCs next to you.

damn, and you guys maintain that this whole optimization initiative will only be a matter of a slightly better framerate for most computers? :p

Well in my initial testing of improving that aspect I only got 1 fps extra (which may seem small but is actually quite a lot) but I need to do some more work on it and I think I can get more than that, but its a huge amount of work what I did which we tbh, don't really have the man power to do all that work and its very complicated and takes a huge amount of time to do it well :(

I hope there are some people who are enthusiastic about doing the Air vehicles because while I'm making a decent amount of attempts per week [Land Veh], I would really appreciate anyone who could help doing the air stuff (since I don't really care about the air vehicles & they're so few/far between on most maps that I can't rationalize doing it all alone for the tiny benefit it will entail).

[b]Issues:[/b]
[list=1]
[*]Geom_2 LOD 0/1: The first LOD(0) has little flaps/wings on the side, whereas none of the other LODs have such a piece of geometry. Forces the LOD switch to occur later than it would have to otherwise. Either remove from LOD0 or add a small bit to LOD1 IMO [[url=http://i235.photobucket.com/albums/ee94/psyrus_uraya/LODs/tunguska_geom2_lod_wings.png]See Image[/url]]
[*]Geom_2 LOD 2: The turret is floating due to the lower geometry being deleted, which results in the LOD switch being very obvious from the front. The LHS of the track geometry is also deleted, which further pushes out the LOD switch. If the wing & floating issue was resolved, LOD switches could probably be halved in distance... roughly.

Phew, just ten to go on land vehicles. I'll be moving on to trying my hand at modeling statics for the norwegian Vadso City (and then perhaps other things). Air vehicles to those who are passionate about them hey (36 to do - they average about 12-17 minutes to properly do from my exp, so 7-10 hours worth of 'work' left).

Oh I moved the pics from my default folder to their own one, had to go through and manually add a /LODs/ thing to each link, so I think that's why they seemed broken :)
