swapd0 Posted February 23, 2014 Share Posted February 23, 2014 It's possible to make the OP to use always the same internal frame buffer? Instead of writing in one buffer while is displaying the other one. Thanks Quote Link to comment Share on other sites More sharing options...
Shamus Posted February 23, 2014 Share Posted February 23, 2014 Sure it can, the OP will display whatever you point it at. You'll still have to update your object list though, the OP will trash that regardless. Quote Link to comment Share on other sites More sharing options...
swapd0 Posted February 23, 2014 Author Share Posted February 23, 2014 I mean to force OP to use only one line buffer instead of two. Quote Link to comment Share on other sites More sharing options...
+CyranoJ Posted February 24, 2014 Share Posted February 24, 2014 I don't think you can - why would you want to anyway? Playfield mirroring? 1 Quote Link to comment Share on other sites More sharing options...

LinkoVitch Posted February 24, 2014 Share Posted February 24, 2014 Why not just write to the main line buffer directly? I did try doing this with the GPU in 16bit RGB. It's possible although my trial code was only fast enough to read and write back to about 40% of a scanline before the OP started to get unhappy. Some optimisations could have possibly increased the amount, it was very rough and ready code Quote Link to comment Share on other sites More sharing options...
