[Qgis-developer] Windows refresh rates are slow

[maaza mekuria]

Thanks Giovanni for the response. It is entirely vector and I find that the redraws to be very slow. 

I made the suggested changes on using render caching and I do not see that much performance gain.

Is there anything else to do to help the refresh speed?

Thank you for your help,

Maaza

rasters or vectors? size? added pyramids/overviews in rasters? did you
tested enabling the "use render caching where possible to speed up
redraws"?

cheers
