Everybody, are begun. I am using DarkBasicProfessional. Each I am learning it a little while seeing Help of DBV113 because I am a beginner. In the forum of the game development speciality of Japan compiler of which does not know even who is making only this forum news, as. Doing it with machine translation from Japanese to English the translation from English to Japanese is safe because there is the knowledge of English. The page of WWW is devising as it is able to read it also in English environment and PDF has included it each Japanese writing style data. If you inspect it with Adobe Acrobat5.x you will be able to read News of Japanese.

There is the case that has been implemented with just as several of black screens, in the Example program that is in help of DBPRO. I was using the video card of NVIDIA Quadro2 32MB to before a little. For example, this program became an error display when it implements the sample program of Pixel Shader. This is not done even the text display, even though it does not become to the error of hardware as it purchased new ATI RADEON9500 128MB. As for this driver, I am using latest Catalyst3.2. Please teach whether or not there is a faulty in these help.

The catalyst drivers are rubbish i could not get any advanced special effects working with them till i downloaded some unnoficial ATI drivers, you can download them from http://users.skynet.be/FCB/ati/ these are much better than the official catalyst drivers so try em out worked for me!

Thank you for teaching that driver software is the cause of a faulty. I am using "ATI RADEON9500 128MB". Thereupon, I would use driver software and "RIVAtunner12.3" of "Omega2.4.07a". The existing problem was canceled. And my video card has come to demonstrate "ATI RADEON9700 PRO" and equal performance.

The solution of an existing problem and I got highspeed 1.6 times.

Hello I used "Patch4" yesterday. I checked that solved the black screen of PixelShader and the LOGO of DB was displayed exactly. It is thought that other reference programs became very quick. Thank you.

Piece of advice. If you're using an online translator, don't.

If you're not, learn better English.

Niether the Radeon nor Quadro2 Card support Hardware Shaders

the Radeon cards support something called Software Shaders, which have been designed within the Drivers to emulate a Hrdware Shaders without using the CPU but graphics card however DarkBasic Pro only uses Hardware Shaders.

you will need any of these,
GeForce3/GeForce3 Ti/GeForce3 Ultra
GeForce4 Ti
GeForce FX/GeForce FX Ti/GeForce FX Ultra/GeForce FX Mx
Quadro4/Quadro4 XGL/Quadro FX/Quadro Quantum

You mean even the Radeon 9700 Pro doesn't support hardware shaders?

Certainly, the Radeon cards (>8500) support pixel/vertex shaders. Try out 3DMark2000SE (or is it 2001SE?... doesn't matter). You'll see some really gorgeous graphics in some of the tests that is pixel and/or vertex shading. Just flat out beautiful. Also, my guess is that DBPro is using a pixel shader to implement "reflection shading" (behind the scenes without any shader commands on your part)... which is why the Face demo displays just an opaque object with 3 vertical color bands on my GF2Go, instead of the reflections like I see on my Radeon 8500.

So, there is always the possibility that you can't use the DBPro shader commoands to make a Radeon card perform vertex or pixel shader operations, but that remains to be seen.

Blanket generality statements about how "Radeon cards can't do (hardware) shaders" is, at best, misleading. My guess is that it doesn't matter if they support hardware shaders or software shaders, blah, blah, blah... either way, DX can use them, and according to the DirectX SDK, that's the way you code them. So what is the point in saying things that people will interpret as "my Radeon won't do pixel/vertex shaders", when it is not true?

The real issue is if/when DBPro will be able to make shaders work on any DX8-compliant device that supports them and... from the sound of it, from the "hints" and "guesses" I've seen (not a lot of solid, verifiable facts have been stated in this thread), when DBPro will support more than just some nVidia cards, or more than just cards that support "hardware" shaders.

But of course, this all just sounds like conjecture to me... we need facts to really learn anything, and we need DBS to tell us where these whizzy-cool features might be expected to actually work, instead of "On Aything That Supports DX8, Of Course!" which is the propaganda one might believe when reading www.darkbasicpro.com.
