From 88d041a6b9958f893312bfd159372c4b4559652a Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Tue, 19 Nov 2019 21:58:17 +0100 Subject: [PATCH] u_vbuf: Mark vbufs incompatible if more were requested than HW supports MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit More vertex buffers are used than the hardware supports. In principle, we only need to make sure that less vertex buffers are used, and mark some of the latter vertex buffers as incompatible. For now, mark all vertex buffers as incompatible.
