One of my main complaints about DBPro is the blurry 2D (except on high resolutions) and general image quality (which is slightly blurry and not as crisp & clear as it should be)

I know that neither of these are necessary because Blitz for example doesn't suffer these problems at low resolutions (by that I mean 1024*768 and less)

My two questions are:

- What causes this?

- How can I fix it or will I have to wait for an update to DBP?

Yes, images on 3D objects tend to be very blurry, even when using the extra loading parameters. 2D images are sharp.

I presume there is some sort of stretching that causes it, and perhaps anti-aliasing settings. If it is a DBPro problem (almost certainly), I dont know if/when it will be fixed.

Good news everybody! I really am THAT good...

It can't be a card problem because I am using a GeForce 3 with the latest NVidia reference drivers (i.e. one of the most common setups around)

Yep, its damn annoying.I almoust gave up my current 2D
game project becouse of this.
Anyways this may help others:
If you grab gfx with the 'get image' command add the (,1)
flag at the end like this: get image id,x1,y1,x2,y2,1
When the gfx is pasted again it will not antialias.

"Yes, images on 3D objects tend to be very blurry, even when using the extra loading parameters."

MrTAToad, could u list those parameters please?

It is the antialising. Db just blurrs the screen, making the edges softer. It shoudn't be too difficult to impliment a command to stop this. Anyway you really should have proper antialising, or none at all. Darkbsic can look really terrible with some objects, although if 3d modelling is hard for you ,blurring can help.

First: Does BB3D use Direct X 8?
Second: If that is true about the antialiasing in DB, I say get rid of it. We should at least have the option. So I agree: Proper or none.

the problem came from the fact that when you open a screen , DBPro must adapt your screen to the default windows resolution.
is windows resolution is not the same than your bitmap , then all is blurred ( because it is scaled to your windows screen sizes.

Only exclusive mode don't have that problem because it does not adapt to windows resolution.

And yet you cant use exclusive mode because of the speed (or lack thereof)...

My windows desktop it 1024x768, and if I run a DBPro game at 1024x768 I get a lovely crisp picture. However if I try and use 800x600 or 640x480 I get awful fuzzy images, 3d or 2d. However if I switch Windows to 800x600, then only DBPro games in that resolution look nice.

This may be a bug, or some sort of Antialaising "feature" the DBTeam added. Either way its ugly and I hope its one of the first things they fix!!!

Until they do, is there a way in DBPro to determine what screen resolution the user has setup in Windows, and then change the resolution of either the DBPro game or Windows to be the same?

That would temporarily fix the problem nicely

I really dont mind antialiasing for 2D (text,mouse pointer
,sprites and images) something I've been missing in DBC.
I agree that it should be improved, but not on getting rid
of this feature, as long as u can decide wether to use
it or not.

freddix,

BB3D doesn't suffer from that problem, and nor does any other commercial game that uses Windowed display that I know. Full Screen Exclusive mode solves some problems, but the text is still blurry.

I think the reason is that rather than using proper 2D for text and graphics, DBS uses 3D to do 2D (I am not 100% sure exactly what this means) - according to the EDGE article. Perhaps this is what is causing the problem.
