Vsync on all the time (UT with the new OpenGL renderer)

Im not a tech head but I have always found that UT is mainly influenced by
your CPU. Well that its seems to me when i have swapped gpu and cpu as
money and failures allow.

What does your UT .ini file have for Vsync? If I remember correctly,
it's opposite of what you might think. IOW, Vsync=False means that
Vsync is turned on.

That was worth a shoot.

As it turned out the ini had nothing about Vsync in the OpenGL section.
I copied the line from the D3D section but no change and it does not
seem to matter if it says =true or =false. Could it be the new OpenGL
renderer needs something else?

Kind regards

Thx for this and the copy below as well. I have been digging a little
bit in the documentation from Chris plus some other stuff I found and
not I know a little bit more.

The "Refreshrate=0" means the render will use the default refresh rate.
In my case that means 100 Hz in 1600*1200 and 75 Hz in 2048*1536, but
I'm not exactly sure what makes thoose refresh rates default. Also you
can set it at the rate you desire but you may not get it!

Based on some settings posted in a forum for the D3D8drv render I have
been able to guess the VSync thing is actually controlled by this setting:

SwapInterval=1

Where 1 means VSync on and 0 means off. However on my system it seems
the setting is just ignored. And that goes for both DirectX and OpenGL.

I shall experiment some more and also try and put together an optimal
settings list. Maybe it will only work with ATI but time will tell. In
this very moment the performance is some 20-30% better in OpenGL on my
system (P4 2.5 Ghz, X1900XTX) - that may be due to the render or maybe
ATI's current drivers are actually better in OpenGL for more simple
graphics like UT. I know they made some great improvements not long ago.

Kind regards

Thanks for the info Bruno.
