• Fixed XPU texture filtering for displacement to better match RIS. RMAN-20904
• The XPU memory requirements of PTex has been greatly reduced, by a factor of almost 4X on complex shots. RMAN-18833 
• XPU now automatically adjusts the texture and ptexture reserved cache allocation size to be the minimum of the requested texture memory limit option, and the actual size needed to store all the highest mipmap level texture tiles in the scene. In cases where there are very few textures in the scene and the requested texture memory limit has been set very high, this can be a substantial memory reduction.
• Some issues in XPU's substitution of <u> and <v> tokens in texture file map names have been addressed. RMAN-19353
• A bug in XPU causing the texture filter widths on non-quad subdivision faces to be off by a factor of two has been fixed. RMAN-21751

• Fixed a bug affecting the invalidation of non .tex textures in XPU where the updated texture would not be rendered. Instead the old texture before the invalidation would be used. RMAN-17686

Statistics

• Fixed live updates for XPU time-to-first metricsXPU stats are now included in the Image Tool (‘it’) HUD.

• Corrected XPU live reporting of XPU maxSamples, timeToFirst* and other high-level metrics.

• Graphs of XPU timer breakdown and ray count breakdown are now available in the new stand-alone stportal app. 

RIS and XPU

General

• Fixed a bug which would cause the renderer to crash if very long (longer than 8MB) string params were passed to it. PRMAN-2789
