Based on the feedback from pull request #1767 I have put in most of
degasus's suggestions in here now.
I think we have a real winner here as moving the code to
VertexManagerBase for a function has allowed OGL to utilize zfreeze now
:)
Correct use of the vertex pointer has also corrected most of the issue
found in pull request #1767 that JMC47 stated. Which also for me now
has Mario Tennis working with no polygon spikes on the characters
anymore! Shadows are still an issue and probably in the other games
with shadow problems. Rebel Strike also seems better but random skybox
glitches can show up.
Initial port of original zfreeze branch (3.5-1729) by neobrain into
most recent build of Dolphin.
Makes Rogue Squadron 2 very playable at full speed thanks to recent core
speedups made to Dolphin. Works on DirectX Video plugin only for now.
Enjoy! and Merry Xmas!!
The Backpatching routines didn't correctly understand where to find the real VFP register from, so in most cases it was using D0.
Fixes bugs in the slowmem loadstore routines as well.
On locales that don't use period as a separator this would break us.
For vector values in a configuration, we use comma as a separator which causes the configuration to balloon to massive sizes due to never saving them
correctly. Loading would then break since it would load a million configuration options.
Fixes issue #7569.
Instead of doing vector operations and throwing away the top 64bits of each operation, let's instead use scalar operations.
On Cortex-A57 this saves us three cycles per vector operation changed to scalar, so this saves 3-9cycles per instruction emulated.
Also puts one less micro-op in to the vector pipeline there.
On the Nvidia Denver I couldn't see any noticeable performance difference, but it's a quirky architecture so it may be noticing we are throwing away
the top bits anyway and optimizing it. The world may never know what's truly happening there.
We can compile with haptic support, and then not initialize due to haptics not being available.
So if we are compiling with haptics, test initializing with haptics and if that fails attempt to initialize without haptics before bailing out.
Allows the UI to easily check the current exclusive mode state.
This simplifies a few checks and prevents the user from ever getting stuck in fullscreen.
