Right now the graphics are expanded from 640x480 all the way to whatever resolution
you have selected, I'm working on it right now

i'm assuming you're working on getting the target resolution to whatever the user
selects. That's awesome. However, when it comes to AA (ie for the sake of this
issue), it would be great if it's actual AA, and not just multipling the resolution
by the AA amount. Just putting it on record :p

Well, I'm not multiplying by the AA, it's going to be actual AA. I'm going to remove
4 unneeded variables from the OGL plugin.

So. I'm trying to get AA in the plugin, but getting AA using GLX is just a pain in
the butt for some reason, anything I try doing crashes or just doesn't work. The
people in the Xorg-devel channel and OpenGL channel in Freenode are too smug to help
me so it may take a while for AA in the plugin.

The whole resolution mod you did is fantastic! games look HD!!! But do you think you
will eventually fix the shadow problems because this is affecting quite a few games
(and making mario feel like he's on lsd or something) there are also occasional
shading problems in smash bros and sonic heroes is experiencing weird shading
artifacts too... so with this new res addon and with fixed shaders, I wouldn't mind
waiting a while for AA...

I will be looking in to the shader problems in a while. AA may work a certain way,
I'll try putting it in and see if it works for anybody in a bit.

If you use FBOs, you can use ogl_framebuffer_object_multisample/blit to do the AA. I
have some example code if you's want to give it a go....

glEnable(GL_MULTISAMPLE_ARB);

no XK.

glRenderbufferStorageMultisampleEXT(GL_RENDERBUFFER_EXT, 8, GL_RGB,
RENDERBUFFER_WIDTH, RENDERBUFFER_HEIGHT);

and...

glBindFramebufferEXT(READ_FRAMEBUFFER_EXT, s_fbo);
glBindFramebufferEXT(DRAW_FRAMEBUFFER_EXT, s_uFramebuffer);
glBlitFramebufferEXT(0, 0, nBackbufferWidth, nBackbufferHeight, 0, 0,
nBackbufferWidth, nBackbufferHeight, GL_COLOR_BUFFER_BIT, GL_NEAREST);

something like that...

omegadox: I tried replacing glRenderbufferStorageEXT to multisample but it didn't
work (also, I only found stencil/depth buffers as FBOs in Render.cpp, that's why I
suggested the simple MULTISAMPLE_ARB).

Which mudlord says no to, ask ector about how the plugin works.

Revision 1320 begins this work. It's hella slow though. It's disabled so I can figure
out why it's slow and get it working with all games.

It's alright. Merged to yours since it's way more informative.
