Hi there! I would like to know if there''s a nice trick or something to reduce fillrate problems? For instance: My rts draws a lot of explosions on screen at once, in 640x480 they work fluently, but look like crap. in 800x600 they work like crap, and look smooth, soft and silky. so, I guess that one approach would be to simply NOT update the graphics often when lots of detail is draw? Question is: How do I do this? if I could combine the draw() function with a sleep(if lasttime I drew stuff took lots of time, I wait a little bit longer this time before I draw) function that would be great. Any ideas? I''ve heard of updating movements according to the time it took to draw the screen, but since my movement code is in a separate thread - this seems unnessesary? I simply want the screen to halt until the loss of time has been compensated (sleeped)... Thanx for replies, I''m in desparate need of help! =/ "Game Maker For Life, probably never professional thou." =)
