Re: ST: Screen Pointer Update glit
Posted by: Orion_ Jun,30.2017-13:43 

Thanks, I tried this (I'm working on ST)
but I noticed that when setting the new screen address in the VBL interrupts, the new screen address seems to be valid only for the next frame, and not the frame that will be drawn at this VBL.
even setting the address in the VBL, I had flickering on one of my effects that was taking around 1.25 VBL to complete, I don't quite understand why, I solved it using 4 buffers swap instead of 3 .. (brute force way of solving things, but well ...)

Message board and comments are now read-only

Due to abuse of the message boards we have put the entire site in read-only mode. That means you can't post new threads or reply to old messages and you can't add comments in VideoDB and PicDB.

Some messages have been erased from reading, but are stored in case they need to surface again.

After 17 years and 45000 messages we're shutting down due to one person.
