Hi, I'm learning darkbasicP. I tested the example about "load terrains" included in darkbasicP. It's uses arrow keys to move the camera over the terrain (it's a highmap). It's uses the commands "SYNC ON", "SYNC RATE 30" at the beginning of the code, and "SYNC" in the main loop.

I observe that the camera movement is no perfect smooth. The texture drawing have not smoothness.

However I tested a example included in Blitz3d with the same highmap and texture and the camera have a perfect smoothness in the movement: the terrain "moves" very smooth.

So I want to know if the use of SYNC is not good or if there is a way to refresh the screen more efficiently. (I post the code below)

Thanksss. Regards.

well u could try increasing the sync rate, idk if that would help though

Video games…they can take you places unreachable, impossible, unfeasible. They put you in the book...they put you in the movie...they put you in a world, a world that before could only be imagined.

Your source code isn't available.

So I cannot really comment apart from the above(increase your sync rate to say 60?)

Also you may want to download Advanced Terrain DLL from this site - with the latest upgrade. Its extremely smooth! - I'm using it at the moment.

It's due to the heightmap being rough, with no smooth gradients, and very high detail (1025x1025),with no scaling at all of the terrain.

if you open help\examples\world\land.bmp you can see that, but basically it comes from not up-scaling the terrain

The new advanced terrain stuff works much better

Last time i had a similar problem i found i was using integer values for positioning instead of float values, would be worth a check as we cant see the code.
