OpenGL - a great speed increase

SDL Development

Is there an explanation why my opengl applications run like 5 times
faster in SDL . These are the ports from plain win code, same libs and
I have a great speed increase, what’s up with that? Got MVC6, WinXP,
TNT2 33.09, the latest SDL, OGL 1.1

I really don’t know the answer to this but it could be that with SDL the
setting were fine tuned which allows OpenGL to run much faster…

Though if someone knows and I am not right I would like to know too!

OpenGL is usually faster than basic SDL when you have video hardware
that OpenGL can use to do it’s thing. Very likely what is happening is
that using OpenGL via SDL means you’re operating on the video hardware
and using straight SDL means you’re operating in/on software.

Sorry about all the post. I got errors saying “Can Not Connect To Sever from
more than 60 Seconds”… So I sent it again and again than it final
connected but it really got the send message a bunch of times! So If more
come sorry! It has been doing it with all the emails I sent in the last hour
(People just started to say stuff)

I’m Sorry!

Why did I just receive five copies of this email (all with different IDs)?
Is this a problem with the mailing list or with your ISP or what?

Sorry for the OT post, but this seems to happen frequently.

Uhh… if the NVidia drivers are installed correctly, you should get OpenGL
"version 1.3.1" (at least IIRC).
No serious driver for Windows reports OpenGL 1.1 as far as I know. Most
likely, you’re using the software renderer that comes with Windows.

SDL requests a hardware accelerated GL context by default. :slight_smile:
