It actually removes the previous hack that read the full target.
Unfortunately snowblind engine game uses big target so the read is very big too (1280x448)
which is killer for the perf. Whereas the game requires only 24x12 texels
Give a 2x speed boost on Champion of Norrath !!!
Games uses very special texture with a lots of repeating.
It is much faster to send the full texture rather than trying to partially invalidate it.
On my gs dump:
FPS: 29 => 68 !
Basically I ran
find . -name "*.vcxproj" -exec sed -i -e 's/_xp//' {} \;
This will likely break XP, but it paves the way on Windows for a PCSX2
that does not require the DirectX redistributables to be installed for
Windows 8, 8.1 and 10 users. Windows Vista and 7 users will still require
the DirectX redistributable files for XInput and XAudio, though PCSX2
should still be capable of running if a user does not actually use either
of them.
All GL4 extensions supported by DX10 class GPU will be soon mandatory
Namely:
* GL_ARB_copy_image
* GL_ARB_texture_barrier
* GL_ARB_clip_control
* GL_ARB_direct_state_access
* GL_ARB_separate_shader_objects
* GL_ARB_buffer_storage
There are likely few games (RE4) which constantly change the FBW register value causing the framebuffer width to be updated at every interval. Adding a safe limit (512) similar to frame buffer height would prevent such constant changes of the framebuffer width when FBW changes once again to an even lower value.
Valid values for png_compression_level are from 0 (no compression) to 9
(max compression). The default is 1.
v2: Use zlib Z_BEST_SPEED (1) and Z_BEST_COMPRESSION (9) defines.
The following patch uses the height value of the display rectangle rather than make an estimation of the Frame buffer height when the game uses a non-referenceable height (or) width.
Don't lookup a depth buffer if depth test is always pass without write
Boost performance on Tekken5 when depth emulation is enabled in openGL
(Tekken5 sets same address for both the RT and the depth but depth is disabled)
v2:
Keep ds if DATE is enabled (some implementation uses a stencil buffer)
Be more aggressive to avoid an useless depth lookup
Texture coordinate could be dummy/float/int integral/int normalized.
Old behavior:
* VS was in charge to select the texture coordinate
* int integral format wasn't supported
New behavior:
* Always compute all formats
* FS will be in charge to select the good format
Impact:
* VS will be slightly slower but it reduces shaders permutation from
little to 0 (won't be bad for CPU)
* FS speed isn't impacted as 2 separate code paths were already required
to support both format
* Rasterizer will be 33% slower but unlikely to be the limited factor of
the GPU
* In future we could directly use the integral format in the FS.
V2: remove useless PSin_t
It would be on by default. Unsafe & fast path.
The hack is a security if someone encounters any issue
v2: update Windows gui file
v3: fix typo in tooltip and linux gui
