From a4003af5c4fe92d55353f42767d0c45de95bb78f Mon Sep 17 00:00:00 2001 From: chen wei Date: Fri, 8 Jun 2018 17:34:45 +0800 Subject: [PATCH] virtio-gpu:improve 3d performance greatly opengl function need fence support.when CPU execute opengl function, it need wait fence for synchronize GPU. so qemu must deal with fence timely as possible. but now the expire time of the timer to deal with fence is 10 ms. I think it is too long for opengl. So i will change it to 20 ns. Before change, when i play Unigine_Heaven 3d game with virglrenderer, the fps is 3. atfer change the fps up to 23.
