A pointer to the containing descriptor heap can be derived from this information.
The PE build of vkd3d uses Windows critical sections for synchronisation, and these slow down on the very high lock/unlock rate during multithreaded descriptor copying in Shadow of the Tomb Raider. This patch speeds up the demo by about 8%. By comparison, using SRW locks in the allocators and locking them for read only where applicable is about 4% faster. --- libs/vkd3d/command.c | 57 +++++------ libs/vkd3d/device.c | 195 +++---------------------------------- libs/vkd3d/resource.c | 166 ++++++++++++++++--------------- libs/vkd3d/vkd3d_private.h | 57 +++++------ 4 files changed, 145 insertions(+), 330 deletions(-)
