put opengl

if you have at least 512 mb ram and a good processor then go with open gl

direct x is only for the suckiest systems

Thanks for the reply. I reckon I have a sucky system with a 1.69 GHz processor and 256 MB of Ram.

try in open gl

i tried both versions, and i havent found a change in performance between the 2

so just put opengl anyways because i dont really believe that there is much of a seeable difference

even if there is a difference it probably just is a slight change in performance

The difference is in performance. OpenGL uses the video board's full capabilities, while DirectX uses software-based kludges to emulate similar capabilities. In other words, OpenGL places the image processing load on the card. while DirectX places the load on the processor, thus the performance hit.

A more detailed explaination can be found HERE.

Thanks for the link to more info about Directx vs Opengl. It cleared up confusion about the issue for me, However your quote raised the issue of whether I"ve found happiness or an stark raving mad. hahahahahahahahahaha or ???

Also add the memory situation. DirectX uses the main memories which means it imposes on harddisks when the memories are full. Whereas, it is not the case in openGL which uses the ram on the display card -- in turn, display card does its work while the cpu and the hdd do their own. So, there is a more speedy and compatible system.

BUT I PROPOSE: Never buy or use these newly created Turbo-cache video cards. These also consume the main memories. They are said, for instance 512K but they are in fact 128K and when 128K is full, it borrows the remaining from the main ram. At these times, the system crashes. When you are told it is 512K, it means, in fact that they are capable of managing 512K. Read their manual on the net carefully.
