Subgroup 'upload' measures the duration of upload calls (i.e. 44 recorded iteration time includes only multiple texture upload calls). 45 Subgroup 'upload_draw_swap' draws a quad with the uploaded texture after 46 each upload and swaps buffers afterwards (i.e. recorded iteration time 47 includes multiple upload and draw calls and one buffer swap). Texture 48 sizes vary from 16x16 to 2048x2048 and include an npot texture with size 49 257x257. Viewport size is held constant at 64x64. 50 51 The amount of draw calls is automatically calibrated to find a workload 52 that produces approximately 30fps. Result is reported as uploaded MTex/s. 53 54 See performance.txt for more details on performance testing. 55
