Display lists
How much faster should they be, they are not any faster with my code for some reason
.
EDIT: i got it, i figured out it only makes real difference if you have high-poly objects in lists, but however, for some reason it still only is about one 6th faster, i had the idea they should be about one 3rd faster. Does anyone know any tips for optimizing display lists?

I bet this is a how long is a piece of string type question. I suppose the speed difference increases with the number of instructions in the build list.
I am suprised by the low increase though, you''re not rebuilding the list every frame are you?

are you?

Nonononooooo !!! I am not
, i am still some sort of a n00b but i don''t make any more stupid mistakes of this type
. Well, i am going to use vbo''s in combination that will speed up some bit. Thanks anyway

Im sure I read somewhere that using VA''s in Buidlists can cause slow down, also pretty sure it uses more memory too.
Trager: i don''t think that would be the case with va''s (and va''s are what i meant when i said vbo''s, sorry about that
) but with vbo''s that is the case. Actually i heard that on many videocards (including mine i found out) VBOs take about twice as much time as simply drawing every vertex.

I found this in the discussion VAs V BLs last week.

On that page somewhere it mentions about combining the pair reducing performance.
Is it the radeons that don''t like VBO''s something like they don''t have the neccessary extensions?

About the VBO slowdown, i have it on every card i tried it on, a GF4 TI4200 and 4400, a GF MX440 and that all with the latest nvidia drivers. I have heard from several other people they had the same problem, but i don''t which videocards they where using. I am not sure the MX440 supports VBOs but the others do.
how many polygons are you calling ''high polygon objects''?? 200,000?
