1.1 Display settings
|
|
|
|
Internal and fullscreen resolution: Since the only internal resolutions allowed
|
|
are also fullscreen resolution allowed by the system there is only need for one
|
|
resolution setting that applies to both the internal resolution and the
|
|
fullscreen resolution. - Apparently no, someone else doesn't agree
|
|
|
|
Todo: Make the internal resolution option apply instantly, currently only the
|
|
native and 2x option applies instantly. To do this we need to be able to change
|
|
the reinitialize FramebufferManager:Init() while a game is running.
|
|
|
|
1.2 Screenshots
|
|
|
|
|
|
The screenshots should be taken from the internal representation of the picture
|
|
regardless of what the current window size is. Since AA and wireframe is
|
|
applied together with the picture resizing this rule is not currently applied
|
|
to AA or wireframe pictures, they are instead taken from whatever the window
|
|
size is.
|
|
|
|
Todo: Render AA and wireframe to a separate picture used for the screenshot in
|
|
addition to the one for display.
|
|
|
|
1.3 AA
|
|
|
|
Make AA apply instantly during gameplay if possible
