Hey guys, I have a problem.

Whenever I build a final game, it is unacceptably slow, hovers at about 25 fps, when I'm getting the full 60 in the editor, I built a blank exe that just prints the fps---still 25, any reason?

Unfortunately, this is something of an known problem with DarkBasic classic executables (including and pre DB V1.13). However, It may been addressed in the recent DB V1.20 update. So you can try that when it's available. See Here.

Here's a few ideas that might help improve the feel of the game from an executable perform.

* Implement a timer based moved solution so game play isn't connected to the physical frame rate.

* Reduce the texture size as much as you can!. Will help in a couple of ways, it'll make your final game smaller (in memory and on disc) and it'll help your GPU prepare each texture quicker (the smaller the faster). This gives a performance improvement because DB (from what i can tell) doesn't cache common textures between render calls. In other words, it gives textures a real thrashing in memory, so by reducing the size you'll help the GPU deal with this thrashing better.

* if you attached media the EXE, then this can takes for it depack on slower systems.

* Disable Vsync (if possible)


Anyway, there's a huge thread on tips for improving speed around here somewhere.

Even if I build a blank exe-no media, just prints the sync, it hovers at about 25 fps.

No, in the editor I'm getting 70 fps plus with my game, I can play soulhunter(dbc game) with a constant fps, I just don't see the problem.

@Satchmo

Instead of using fullscreen mode, try using windowed mode. On my machine I've noticed exes run at about the same speed that they do in the compiler when they are run in windowed mode.

The following script runs somewhere between 500 and 550 fps in the editor and between 160-170 fps when made into an exe (DBC 1.13 2002).



Now, adding the set window on command, it runs at about 450 in the editor and at between 440 and 450 as an exe. I think it slows down a bit in windowed mode in the editor because the screen depth goes up to 32 (the bitdepth of my desktop).



Enjoy your day.

Of course it's possible. I think the highest possible fps is 1000.
The figures I posted are from my computer - yours probably has a little more juice in terms of the processor speed and/or graphics card ability. My post is just to show the difference in speed from full screen to windowed mode.

Enjoy your day.
