From: Tim Rowley Date: Wed, 17 Aug 2016 15:45:37 +0000 (-0500) Subject: vbo: increase VBO_SAVE_BUFFER_SIZE from 8k to 256k dwords X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=edd688d986da17b99ee8e4bc7c4e62fc2af5ed0e;p=mesa.git vbo: increase VBO_SAVE_BUFFER_SIZE from 8k to 256k dwords Increases the performance of legacy geometry-heavy apps still using display lists. Performance increase for a targeted testcase is on the order of 8x, and applications like ParaView 4.x (5.x uses no longer used display lists) improve by about 10%-20%.
