Hello folks, I got a mystirious speed problem with my rendering-method. I''m using dx8.1. Rendering 2 small Objects with just one texture each, gets average 200 FPS. (P4 1.7, GF4mobile) If I''m running my compiled exe on my other machine (P4 1.8, GF2) the average FPS is nearly 30. I''m an absolute beginner refering to dx8, so it will be very nice if anyone of you could give me hints what to change. btw: HAL-Device is registered on both machines; I compiled with debug-dll''s; Hope to hear from you, tia, :-) Python Spin the wheel of fortune - or learn to navigate.

Too much renderstate changes (can tested by setting pure device, when pure device is slower than this is a problem,pure device don´t test if the renderstate is needed)
Too much drawprimitiv calls
Too much texture changes
Wong use of TnL, or Vertexshader
Device is not init right(no hardware device ??)
Memory Pool is wong like textures or Vertexbuffers in systemmemory

Maybeyour initialization method is good for one machine but dosnt work so well with the second one.
