freshplayerplugin is smoother on intel GPUs then nvidia

[gaining]

This is not really an issue but an observation. There are 4 PCs on which I test this at home using this site: http://www.miniclip.com/games/gas-and-sand/en/ to find out how smooth the pcs can play this 3D flash game. It is always smoother on Intel GPUs then nvidias . There are no lags at all on intel HD 3000 and 4600 but on nvidia gforce 8600GT (I know that one's an old GPU but game run smoothly in chrome using it) and nvidia nvidia gforce 840m. I have the libvdpau1 driver installed.

This is my freshwrapper.conf file stored in /etc:

# Configuration options for FreshPlayerPlugin

# This configuration file is optional. Wrapper will search for it first
# in ~/.config/freshwrapper.conf, then in /etc/freshwrapper.conf.
# If wrapper fails to find configuration, it will use default values,
# which you can find below

# Audio buffer is used to continuously provide sound adapter with data.
# Values too low may lead to buffer underruns and stuttering.  Values
# too high will lead to noticeable latency. Usually plugin selects size
# on its own, but you may override bounds here

# lower bound for audio buffer size, in milliseconds
audio_buffer_min_ms = 20

# higher bound of audio buffer size, in milliseconds
audio_buffer_max_ms = 500

# output sound through JACK. If enabled, only JACK will be tried, and if
# your machine doesn't have it, there would be no sound, and no sync

# a number of location where it could be. Usually that's enough, but if
# not, you should manually enter the right path. Multiple paths could

# if zeros are used here, freshwrapper will select minimal width and

At the moment graphics code changes GL context before and after each GL command. And while integrated videoadapters don't feel that so much due to all data reside in the same memory, discrete can have severe performance degradation. Driver will have to sync state between CPU and GPU memory.

Commands need to be queued with smart flushing, as done in Chrome/Chromium. Perhaps, I'll do that some day. Or reuse code from Chrome, once I get how it works.
