Available Video modes

[jamesd256]

Hi,

I'm trying to run Oolite on a UMPC. It runs Quake 3 at around 20 fps, so I was hoping to get decent results with Oolite.

So far, I have failed to achieve that, but I think this is largely since I can't access lower resolution modes.

My question is, how does Oolites determine what OpenGL resolution modes are available. On my laptop, I can select as low as 320x200 in Oolite.

What seems inconsistent is that on my UMPC, Quake 3 offers me a different set of OpenGL modes, with lower resolution ones available.

The OpenGL modes available don't match the desktop modes available either.

(With the usual apologies if this has been answered, I couldn't find anything.)

Thanks,

James

Oolite on PC uses standard SDL library functions to get from the operating system the display modes available. All of the modes found are listed on stderr.txt.

It is strange that the modes reported by Oolite don't match the desktop available ones. I guess it may be due to reasons specific to the UMPC. But I don't think that Oolite on anything less than 320x200 resolution will be playable anyway.

Additionally, Quake 3 at 20 fps is not impressive at all, really. If you get this kind of performance on such an old game, then I'm afraid there is not much to hope for in regards to performance with Oolite. Not sure what OpenGL support you have, but first thing I would do would be to upgrade the graphics drivers to the latest version.

If you want, can you please post the first 50 lines of your stderr.txt (located in the oolite.app folder)? Some enlightening information may be found there.

Thanks for the reply.

I got 320x240 on my laptop, not my umpc.

If I could get 320x240 on my UMPC, I would be happy, but it won't gop lower than 640x480, as you will see from my stderr.

BTW, I am fully aware how crappy 20 fps is in q3, but it does indicate some open GL rendering ability.

As far as i can read, your Graphic card got a complete lack of any hardware acceleration for Shaders.. so they should be turned completely off...

Where as it does to appear to support Hardware acceleration for polygon drawing (GL_EXT_vertex_array ,GL_EXT_compiled_vertex_array )


it is also a good idea to set all of your options to the fastest setting... for example i can read that your card cant hardware accelerate anisotropic filtering...

All in all your card can render 3d objects, but not very well... since most of the calculations required by modern games has to run by the CPU rather than the GPU... which is also why you get 20 FPS in Quake 3...

Cheers Frame...

[jamesd256]

Thanks Frame.

The tropuble is, I can't find any documentation that explains how to set all the graphics options.

I would still love to know how to access 320x240 too.

[jamesd256]

Just FYI, everything is running great on my UMPC now.

I'm running a program called GLDirect which emulates OpenGL via DirectX hardware.

It upgraded my OpenGL support to 1.4, gave me more extensions supported and the framerate has gone up a bit too.

I havn't measured the difference in Oolite, but just for reference, it has about doubled my frame rate in Quake 3.

Anyone who thinks the game should run better on their HW, I highly recommend you experiment with this tool.

[jamesd256]

Sorry to flood the thread, but SciTech have just replied to me saying the product (GLDirect) is no longer in development, but the latest version is now completely free!

Here you will find the full version, plus a free registration code:

ftp://ftp.scitechsoft.com/gld

In addition, they plan to release the code as open source.

Never mind, two posts wouldn't yet be considered flooding.

But if you want to avoid a double post on the same or a similar issue, there is the edit-button at the top right corner of each of your posts. Just click it and edit, add or delete what you want, then post again. If you edit the last post of a thread, the fact of being edited wouldn't even be visible to the other readers.

Ok, thanks for the info.
