I was doing some testings.(test.cpp and bitmap attached.)
I created a tint to set the opacity in 50%, it works in D3D, but it does not work in HARDWARE.
Additive = true
In FULLSCREEN and D3D after the program finishes, my desktop remains in 640x480, and the program continues resident in memory.
In FULLSCREEN and HARDWARE my monitor shows this message "238Hz frequency not supported"
I also have this problem with some OGL and OL games. Is there a way to force a standar refresh rate like 60, 85, or 100hz? In AllegroGL I use Allegro's request_refresh_rate(x) to solve it, but this time that did not work.
tileBlitToScreen works fine in HARDWARE but it shows something weird in D3D mode.
This is a setting in your driver panel.
I set antialiasing to 8x but it looks aliased.
If I set antialias to Application controlled, can I control it with some lines of code from my application?
