Three root causes identified from wowee.log crash at frame 134368: 1. processPendingTransportDoodads() was doing N separate synchronous GPU uploads (vkQueueSubmit + vkWaitForFences per texture per doodad). With 30+ doodads × multiple textures, this caused the 489ms stall in the 'gameobject/transport queues' update stage. Fixed by wrapping the entire batch in beginUploadBatch()/endUploadBatch() so all texture layout transitions are submitted in a single async command buffer. 2. Game objects whose M2 model has no geometry/particles (empty or unsupported format) were retried every frame because loadModel() returns false without adding to gameObjectDisplayIdModelCache_. Added gameObjectDisplayIdFailedCache_ to permanently skip these display IDs after the first failure, stopping the per-frame spam. 3. renderM2Ribbons() only checked ribbonPipeline_ != null, not ribbonAdditivePipeline_. If additive pipeline creation failed, any ribbon with additive blending would call vkCmdBindPipeline with VK_NULL_HANDLE, causing VK_ERROR_DEVICE_LOST on the GPU side. Extended the early-return guard to cover both ribbon pipelines. |
