The New SuperTuxKart Looks Better, But Can Cause GPU/Driver Problems

[nanonyme]

But people probably prefer Witcher 2 rather than Super Mario Bross

Support OpenGL 2.1 would be great. A lot of people which I know still have graphics cards with OpenGL 2.1 only. But after some time this will be deprecated too. If we have limited time for programming, better is to improve GL3 based engine to make it working well instead of trying to support everything (which would mean no progress).

I'd rather say 2.1 is already gone, some still have such chips. 3.3 is now but moving fast to deprecated. If you want to make a game for future audiences (like AAA games usually are), you'd at this point target 4.6. It will likely get common by the time the game is done if you're making a new game engine.

Cut userbase just because of special effects?!.. People still prefer Jagged Alliance 2 to all newer versions, you know?

All HD2XXX (r600+) support at least OpenGL 3.3. So it is the minimum requirement. On the nvidia side, 8XXX up is OpenGL 3.3 Granted, 8 years old, not 10.

Serafean.

Ah i might didn't explain what i am really thinking i talking about clear 2.1 path that still works in this beta... that should probably work even on r300 hardware, only "requirements" are npot textures that hardware misses, that is why i virtually raised requirements to HD cards and not beceuse those have otr not GL3 support .

So 2.1 advertised GL version with npot textures as minimum, well name those cards if you can i can't - some nvidia "2.1" have it and completely missed from r300 ati hardware

Nope, the "advanced pipeline" is completely broken for me. Even these settings like http://i.imgur.com/63eSogP.png make it look like http://i.imgur.com/SThxBqE.png

That is how looks like to me to with the same settings and any other when advanced pipeline checked, but with unpatched mesa of course.

Applying just this one https://freedesktop.org/patch/38706/ fixed it.

llvm is 3.6-svn224505, floated point textures are enabled...

Odd...Can you fill a bug on github ?

https://github.com/supertuxkart/stk-code/issues

With your gpu, mesa version and log from stk ?

By the way did you build Mesa with floating point texture ?

And that texture compression do weird things too on radeonsi, basicaly effects on 4 with only disabled texture compression should be max safe settings currently... that works fine here

For settings 4 it works (besides those lines on any), on 5 there are many other problems.



It can also be problem in game (engine) it is so new(ly forked), i found Bloom effect makes GPU faults on Windows and Linux with Catalyst, the same with opensource radeonsi, that should be bug for engine.

See the list of "known driver bugs" for Antartica engine, no vendor excluded

I was talking about shadytoy.com, and so was the radeonsi user. The FOSS drivers on our systems can't even run that site.

I'm glad to see some more improvements to SuperTuxKart. The game itself isn't half bad, but the graphics really needs an upgrade. I've been following the development for a while and I can see there has been some improvements to lighting and shadows. I don't however like the changes to use HDR/Bloom, which most games uses nowadays. Utilizing newer OpenGL is a must, especially when writing efficient shaders. The game still suffers from terrible low polygon count, texture resolution and poor animations.

No, all software should be written against the specification. If the drivers don't behave according to specifications, the drivers themselves needs to be improved.

Why not create legacy renderers? There are so much devices! Obviously Opengl 1.x is out, but 2.x? Cut userbase just because of special effects?!.. People still prefer Jagged Alliance 2 to all newer versions, you know?

[brosis]

You must be kidding me. The commercial variant of OpenGL offered by NVidia is hundreds of man years ahead. There is no comparison.

Try going to http://www.shadertoy.com and watch the open source drivers implode....

These should serve as a basis for improving the oss drivers.

I'm not an NVidia fanboy; I'd like Sandy Bridge to work well - its just that it doesn't...

For a game that's pretty much the poster child for FOSS gaming, that's poor. If anything it should be the other way around, they should be recommending the open source drivers and it should have been developed to work on those first.
