Hi

sometimes on startup, gzdoom with flash twice when it starts up and have double the shader init messages and in play the screen flickers like mad. no idea why it happens.

he's what i do

start gzdoom
see it flash once the title screen and init messages
then back to the desktop
then back to gzdoom and more shader init messages
start a game
game is flickering like mad when moving about, like a double image and some strage ghosting.

using an ATi X800XT with Catalyst 6.5 (Latest to date) been happing for a few versions of GZDoom now.

Make sure that in ATI's CP/CCC that Mipmap Detail Level is set all the way to Quality.

there on High Quality, for all settings

edit:ok wtf setting it to Quality and not High Quality Fixed it.

whats the root problem anyways?

Well, when you update the drivers/software, the settings can be fuxored. Sometimes you may want to reset settings to default and then manually change them afterwards. (The app problably uses its own settings independant of the actual value, which can cause negative effects.)

I should've said setting make sure the setting is at High Quality though. Try doing the above suggestion first (reset settings to defaults), and if it doesn't work, use the Mipmap value that allows GZDoom to work correctly).

I have a Radeon 9800 Pro with the latest CATs (6.5) and High Quality works fine.

just tried again and its playing up again, just installed 1.0.11

edit:just deleted my zdoom-name.ini and it still happens at random

I get this effect when I try to run two OpenGL apps simultaneously. Do you have anything running in the background that hijacks the GPU?

thats the thing, there's no other apps open at the time, its almost like gzdoom runs something twice
