| If your game runs at different fps on different computers it is most likely not a fault of the code logic. - driver/engine issues (dx7 on windows8, opengl with gpu drivers which do not like opengl) - vsync on/off and wrong flip-calls. If the FPS is on one 59/60/70/... and on the other one 220, it is vsync. But if the fps value are lower than a normal refresh rate, this isnt the source of the differing fps values in your case not used: wrong timer logic, so your manual delays wont work on some computers with negative time values. Like said: not used in your code. bye Ron |

| If you're using Blitz3D (and I don't know because you haven't said - it helps to post in the correct programming forum for specific language issues), there was an update to resolve speed issues under Windows 8. Go to Account>Product Updates, and download at least Blitz3D v1.107 (a full install of Blitz3D 1.108 is also available but I've no idea what the differences are). |
