Thank you all for your advice and help. I have been trying to move all the code now to .convert() and to render updates and dirty rects, and I already see an increase in speed on windows at least. I will work at making the code optimised and will let you all know if that does the trick under ubuntu with my video card, although I should just inverst in cheap card anyway.
I am also using an old intel (i810) onboard video (this time under debian) with everything set up correctly I get terrible performance. I tried pygame, SDL and C and OpenGL and C and it's terrible all along with C + SDL only offering a very slight increase over pygame of under 1fps. I came to conclusion that it's all the display drivers fault. When I had a similar chipset and similar spec cpu in a compaq laptop I got what I remember as better performance under XFree86 then I do now under xorg. Perhaps there is some newish option that these older drivers don't support or then again perhaps I just have fond memories of that machine and wish I could afford such good quality up to date hardware these days :) Neatly written dirty rects with one call to pygame.display.update per cycle seems to offer the best solution. I managed to get many hundreds of small blits (simple particle engine and sprites) per second to run at 100fps without throttling on a Celeron 600, i810, 256mb ram using dirty rects when calls to flip each cycle rarely got into double figures 'walking' a block around the screen. sparkes -- Steve 'sparkes' Parkes - tshirts http://nerd.ws - code http://zx-81.com Autistic LUG http://autisticlug.org - blog http://sp.arkes.co.uk
