Vulkan: Break renderpass when switch from query to non-query getQueryResult will wait for query result to be available, which means a potential CPU bubble if the result is not yet available. On tiler GPUs it will at least wait for renderpass to complete. Usually query enabled draws are very tiny (usually just draw a point to see if it is occluded or not), and query disabled draws are expensive. Some apps do issue a glFlush when switch from query draw to non-query draw, but app like dead_by_daylight does not issue such flush. In order to reduce the bubble, this CL ends renderpass and issue a flush when we switch from query enabled draws to non-query enabled draw so that the result will be available much earlier, this reduce the CPU bubble. This result in dead_by_daylight frame time improves from 5.45ms to 3.5ms (35% improvement).
