Hi,
thx for the hint, sometimes they help ;). On my laptop it did not work, I tried
every Threadmodel I could find in the viewer. No changes.
But i realized that this error in fullscreen is just the lower 2/3 screen. In
the top 1/3 the object are fine.
I tried to update my driver, but intel d
Hi Andreas,
I have pretty new Intel board on my laptop and got into few problems with
the StatsHandler - just accidentally I changed the threading model of the
Viewer and I got it back to normal. This is a hint no clue why it is
happening but maybe worth of try
cheers,
Nick

Of course! I am certainly not claiming that hitting opti

Then I am really at the end with ideas :( Perhaps Jordi will know what
could be going on there.

That it certainly does. Modern LCDs are not tied to the VSYNC/HSYNC and

I have 3D scene set up in osg, and I'm trying to use oculus rift to view the
scene. What I'm trying to do is "calibrating" an initial position using
makeLookAt and grabbing the rotation in order to focus the camera on a specific
spot of the scene;
The problem arises when I then attempt to stack

Hi Robert,
The latency values for SYNC_SWAP_BUFFERS=ON and OFF where exactly the same for
the custom settings.

One major problem with the Intel drivers is that their products are
typically EOL'ed (end-of-lifed) three years after first release - at which
point they stop receiving driver updates (not even bug fixes).
You can see the problem with the integrated graphics in Intel's Sandy
Bridge chips (introduc

Hi Andreas,
What release of Intel drivers are you running?
I recently experienced issues with an application on various Dell
notebooks and Intel NUC barebones (all HD4000-based) where texts
printed with glRasterPos3 were not displayed at all with driver
release 8.x. Upgrading to release 9.x (from

Hi again,
I also tried Roberts suggestion about using the trunk and
OSG_SYNC_SWAP_BUFFERS=ON.
To get better averages I took the measurements over 100 cycles:
Recorded data:

OSG 3.2.1 + Nvidia Defaults + VSync On:
min_latency = 59ms
max_latency = 65ms
mean_latency = 62ms
