Useful for things that should be run ASAP even if the threadpool is full,
at a small extra cost. (Not recommended for very small tasks).
Considering using this to resolve the deadlocks in #16802.
Slightly reduces the number of unique vertex shaders but doesn't do much
for the pipeline count, as the fragment shader has a tex flag. Still
worth doing for the simplification.
Extracted from #16759 and bugfixed. Fixes a leak of Vulkan pipelines.
I guess another way would be to queue the variants for destruction at
the same time as we queue the callback, but I like this better.
Instead of just the vertex type.
This will allow things like the vertex decoder supplying defaults, in
order to reduce the number of unique vertex shaders at the cost of
slightly larger vertex data.
This doesn't actually do that yet though, it's just a refactor that can
be done separately.
Part of #16567
Will resolve a future issue in the multisampling PR, where the
GPU_USE_FRAMEBUFFER_FETCH flag changes at runtime if you switch between no AA and MSAA.
Just figured I'd get it in separately for safety.
Hardware tessellation + uberlighting + clamp was exceeding the buffer,
causing memory corruption. Let's try to catch it, but also increase
buffers to be safe.
This reduces the number of vertex shaders and thus pipelines by quite a
bit more in a few games, like Tekken and GoW, continuing the fight
against shader compile stutter.
The perf impact should be minimal if not positive due to less pipeline
changes.
GLES fixes
Make the vertex input declarations match (always declare fog input). Fixes D3D11 validation
Tess fix
In #16104, we drastically reduced the number of shader variants for
games that use flexible lighting setups. I looked at a few games and it
seems that a lot of games have the same shaders with fog on/off, while
fog is super cheap to compute. So let's just always do it, reducing
vertex shader variants further (though the amount of pipelines will probably
remain the same, since we still specialize the fragment shader).
Might also be worth adding a dynamic bool for the fragment shader, but
if so, doing it separately.
