Previously the dedicated custom resolution scaling equation was ignored for the second SetScale() call, generalizing the equations will also fix the DMC scaling issue on custom resolution. Also remove unnecessary checks for null on scale factors. The possibility for having a null scale factor value only exists on custom resolution and it will only happen on cases where the output circuit isn't ready yet. So the ideal way would be to handle all the required conditions of output circuit on "m_renderer->CanUpscale()" itself.
Just clear the buffer. The generic solution will be a copy from buffer A
to buffer B But it requires
1/ a big buffer A (otherwise it would overflow)
2/ a line width rescaling (+ the upscaling mess support)
It must work fine without it now.
From the google code comments:
It would be nice to test those games
* Ar Tonelico 2 (line in sprite regression?)
* breath of fire dragon quarter (overlayed user interface in the game)
v2: update Dx code to use the good format
It creates a regression on game that uses a small temporary target to
upload textures of various sizes. Inital code was done to handle direct
frame write (background, FMV) so big target
CID 168626 (#1 of 1): Uninitialized scalar field
uninit_member: Non-static class member m_end_block is not initialized in this constructor nor in any functions that it calls.
Update done on f712c5c6d0
Previous code use the size of the draw to compute latest block. I
don't know why I use .x/.y which are the origin offset so the start of the block.
Fix#1457 (GTA)
The game uses a depth format for a pure color buffer (cokes do ravage
in gaming industry)
However I'm really afraid that it migth break another effect in other games.
* Improve frame buffer height management on custom resolution. Width seems to be fine with the same size as scaled image output.
* Prevent offset issues on Persona 3 based on the data from merge circuit.
Note: Fixes custom resolution upscaling on ICO 50Hz/60Hz mode when large frame buffer is enabled. previously 60Hz mode only displayed half of the screen and 50Hz mode only worked due to the scissor hack.
* Ignore Frame memory offsets for calculating dimensions value of display rectangle.
* Remove hack which limited scaling size based on the scissor value.
Note: With the following commit, SilentHill 2 now properly outputs the desired resolution by the users on custom resolution. Previously if we set 1024 x 1024 , it'll output a lower height value which was caused by the hack removed on this commit.
Issue1: Depth buffer is wrongly invalidated only the first page is detected.
Issue2: First page seems to be partially written. Could be a GSdx transfer bug.
Anyway, invalidation only support a page granularity.
So here a quick workaround that will clear depth buffer in case of very small partial write.
Might worth to check regression on nocturne/digital saga
GSOffset is already based on a lookup of PSM/BP/BW. Coverage only adds
the size parameters (so only 256 possibilities)
It replaces the hash lookup with a free array access.
