sf::RenderTexture issue?

[Krofna]

It appears that sf::RenderTexture only work on modern graphic cards (It failed to render texture on ATI Mobility Radeon X1600).
Since I'm making tile-based game, I need more portable and efficient way to do this.

It is to my understanding that drawing tile by tile(between 24*32 and 24*32*2 tiles, depending on number of world objects) on each frame is very slow, so I'm now out of ideas.

How should I fix this problem?

EDIT: This is code

sf::RenderTexture will be fixed in SFML 2.1, it should work on all hardware.

But download a recent revision of SFML 2, and use the new sf::VertexArray class. It allows to gather many primitives (ie. your entire tiled background) in a single entity, without the need to pre-render it. And it avoids the maximum texture size limitation that sf::RenderTexture has.

I failed to find a way to load tiles from file into VertexArray. But it doesn't matter for now.
When will SFML 2.1 be avaliable?  I need it to work on all hardware in  6-7 weeks

Hum, you should look at examples and read the doc to understand how it works

SFML 2.0 is not even released yet, and I have no idea whether the RenderTexture bugs will be easy to fix or not. So don't rely on it being ready in 6-7 weeks. You'd better learn how to use vertex arrays, I've added them especially for this kind of use case.

I have the same issue on my laptop, which has a ATI MOBILITY RADEON X300. It's from the same series so I think it might be related. I would really like this to work too, because I use my laptop a lot to show stuff to people. And i have a couple programs that rely on RenderTextures

Just tell him the truth: It won't be fixed in 6-7 weeks!

At least if you look at how reeeeeeeeeeeeeeeeeeeealy slowly SFML 2 is getting to it's release point (if at all).

There are also multiple forum posts about how to use VertexArray with various (good) examples.

Haha this post is from January so I know it wasn't released in those 6-7 weeks (hopefully in the next though )
I just wanted to add some information about this issue, because it seems to be related to ati graphic cards (I'm on windows 7 with the 2.0 rc by the way) on my other machine with a GeForce gtx 560 the RenderTextures work fine.
