I have a copy of darkbasic pro but it runs slow on all my pcs when i hit F5 or make EXEs. even the demos that came with it runs slow so its not my code. I also have DBC and it runs perfect at 40 FPS I have a have a Gforce 2 APG graphics card and a 800Mhz pc
with Win 98SE 940MB of RAM PC 133. Can someone tell me what wrong is it a bug in DBPRO or do i need to upgrade my OS.

GeForce2 is the main culprit, following by the PC and Windows 98SE

If I were you, I would get a new computer...

DBPro is a lot more demanding on the graphics card than 'Classic', mainly because of the extra power.

I had a similar problem before.

Firstly make sure you have the latest patch installed,patch 4 has a major speed increase. If that doesn't work you may have to get your motherboard upgraded.

That's what I had to do,

Hope this helped.

Are you guys sure its the Graphics card and the WIN 98SE. Because I also have a Athon 1.2Ghz processor with windows ME and its still slow. If I dont get the problem solved i think I'll just stick with DBC and darkmatter or switch to blitz bsaic 3d thank anyway.

DBP runs fine on my machine (well, alot better than you'd expect to be honest):

P3 450 mhz
256 mb sd-ram
nVidia TNT2 32 megs
WinXP Pro

anyway, could you say what fps you get using one of the demos?(roadterrain will do, just adapt it so it displays the fps).

i get a healthy-ish 25 fps on my machine.

come to think about it, my friend has a faster machine (800mhz, 256mb ram) with a geforce2 and dbp ran slow for him, i remember doing the exact same test and getting 9fps on average.

Its a buid in 128 bit AGP CARD. But if thats the problem why does Blitz basic 3d work so smooth are they not more are less the same or duz DBPro need more power. If thats the case why switch to DBpro not many people have hi performace PCs. If I make games in DBC or BB3D i could produce dbpro type games without people having to get a new PC. am i right or wrong. Someone tell me why pro?

For the road deme I get about 15fps on a 800mhz with 32mb tnt2 and 512mb ram. I would put most of the blame on the grafics card. If I where to put a decent card in this machine the fps could tripple.

Dbpro is a fairly new product compared to blitz and uses directx 9. If you just want to write games for old slow comps then blitz may be a better choice over dbpro. Dbpro needs to work well on and support the latest hardware even if this is at the expence of older hardware.

Even a slightly better grafics card can make quite a bit of difference

Why Pro ?

Because its powerful - which is why it needs fairly beafy computers. Dont forget that if its not DX8/9 compatiable, its going to struggle when DX needs to send info to it.

Built-in cards are a no-no - aside from the fact they're normally cheap (and take up system RAM), they tend to be slow. In DX8 (I dont think its true with DX9 now, which I think now expects everything to be done in hardware), for some effects it would try and do complex things using software, and not in the hardware. I haven't read my DX9 SDK for a while, so the above may be slightly dodgy.

On top of that, some of the DBPro routines are still using debug code (or has that changed now) ?

1) Update your video card drivers to the latest version available
2) Optimize your 3D card settings (turn Vsync off for more speed)
3) Use lower resolutions (higher resolutions means more bandwidth is needed and this is bad for older cards).
4) Use lower color depth (again a bandwidth issue on older cards).
5) Make sure you have the latest version of directX installed (currently that would be DirectX 9.0b)

These 5 tips don't just apply to DBPro, but any game that you want to play on your computer.

For DBPro specific tips...

1) Make sure you have "Sync Rate 0" in your program to give you even more speed (just help show its not a computer issue).
2) Use "Fastsync" instead of Sync
3) Use Patch 4.1 or greater on the retail version of DBPro
4) Optimise your code as much as possible (you want to do this in any language).

Sync Rate 0 on some GeForce cards causes a 1 second delay before your program responds to a movement of the mouse. If this happens, use Sync Rate 60 and the problem disappears!

Back when DB Pro first came out a lot of people complained about Geforce 2mx cards running slow. Most of the problem then were fixed by updating the drivers to the lastest version. I have a 1gh Celerion and a Geforce 2mx for one of my computers and I get decent speeds of 40fps+ on most the demos that came with DBPro. It is not the card. Have a laptop 700mhz with 8mb video ATI RageM card and still can get 10-15fps on some of the demos if I can get them to run at all due to the limited video memory, so don't see why computer with a 32mb Geforce2mx couldn't do a lot better.
