These games seem to constantly have unused vertices, and this is worst shown in the Shadow Pokemon purification cutscene. The Shadow Pokemon purification cutscene is even worse on XD with forced single core mode, as instead of having FPS dropping with VPS staying 60ish, it will drop both, resulting in audio stuttering. Turning on CPUCall seems to have a 7/8 reduction of draw calls for that cutscene (~800 -> ~100), doubling performance. Many other areas of the game seem to benefit from this setting too, having some kind of performance boost.
See https://bugs.dolphin-emu.org/issues/13248. This is needed for the menus to work properly (not run at 1FPS and render incorrectly). Additionally, immediate XFB causes flickering.
Fixes dynamically changing dpi scaling.
Load resources from svg if possible.
Currently svg support is not in Qt build in Externals,
and image files need to be added later.
This extension is currently required to get good performance.
So instead of maybe triggering a GPU hang, let's just disable the shader and show a warning instead.
Sadly our postprocessing framework does not support reporting a warning, so the way to display the warning is a bit hacky.
But this is an ascii-art shader, we already have a font in the shader, so let's use it.
Dolphin had a nice but horrible slow asci art shader.
Beside being slow, it used the font from dolphin's old OSD implementation.
So it was also broken after the VideoCommon redesign.
This patch reintroduces the (almost) identical method for the asci art generation.
However with many improvements:
* Inline definition of the font, so no external dependency any more
* Optimized performance by partial unrolling with CSE'ing some memory loads
* Shader subgroup instructions, so 32 times faster on desktop CPUs on Vulkan + OGL (no D3D support)
* Option to select character size by internal or window resultion
* Dropped the last row of pixels of each character (only modification of the outcome)
Cubivore had an old issue before Hybrid XFB was merged involving the screen shifting left. Immediate XFB actually brings the issue back. It should be disabled for this title.
These games greatly benefit from CPU Culling, and there isn't much reason
not to just blanket enable it for all users. There is no case where you'd
want it disabled.
A call to GXCopyDisp(), made once before the title screen for no
apparent purpose, is causing heap corruption, but it isn't observed on
real hardware thanks to the data cache. Skipping the call works too,
preventing a crash on the main menu.
This patch substitutes field rendering with full frame rendering in the
NTSC and NTSC-J versions of Eggmania. This allows Dolphin's
"Force Progressive" hack to work with this title.
