- Newer nvidia drivers are not exposing IMMEDIATE present mode unless you change options in nvidia control panel
This can cause severe performance degradation unless the vsync option is set to "off" in control panel
- Some games overflow the program buffer e.g Resistance games
The observed overflow is one instruction longer, likely an engine bug
with counting instructions
- Tags framebuffer resources on first use (when on_write is called to verify memory)
- Texture cache now selects the best match and even sorts atlas writes with memory write order to avoid older data showing over newer one
- Some formats are proven to ignore swizzle flag
- DXT compressed textures
- COMPRESSED_BG_GB class textures
- Some applications are using swizzled wide integer formats so those are confirmed to swizzle
- Use proper time checking; depending on what is being done one 'tick' can
be almost a millisecond long or several nanoseconds
- Avoid spamming the system timer unless necessary
- A possible deadlock is still present if rsx is trying to get a super_ptr whilst the vm lock holder is in an access violation
This patch makes this scenario very unlikely since each block need only be touched once
- Implement forced reading when calling update method to sync partial lists
- Defer conditional render evaluation and use a read barrier to avoid extra work
- Fix HLE gcm library when binding tiles & zcull RAM
- Do not do a full sync on a texture read barrier
- Avoid calling zcull sync in FIFO spin wait
- Do not flush memory to cache from the renderer side; this method is now obsolete
invalidate_range_impl_base does not mark all textures that will only be
unprotected as dirty when doing a deferred flush, since that is done by
flush_all.
However, if there are no sections to flush, the deferred flush will
use the same code path as non-deferred flushes for unprotecting textures
and forget to mark them as dirty.
This commit fixes this bug.
The existing implementation restarts the loop immediately after
finding a range_data instance that updates the trampled_range.
This commit refactors this method to continue the loop with the updated
trampled_range, and then repeat only those range_data instances that
were iterated through before the trampled_range was last updated.
As a result, the number of total iterations required is reduced.
