I have a huge problem displaying the austrian Basemap.at WMTS Service in QGIS 2.4. When I add the service, qgis logs multiple errors on failed tile requests. When I zoom into the map, it is displayed in a very poor quality (see screenshot).
I really don't know how to fix this problem - can anyone tell me how to increase the quality of the tiles?

WMTS URL: http://maps.wien.gv.at/basemap/1.0.0/WMTSCapabilities.xml Basemap.at Scrennshot: Poor Quality

UPDATE 1:
I tried setting the resampling methods in QGIS to Cubic/Average, as you guys advised me to and compared the result with the same zoomlevel in ArcGIS. In this screenshot you can see the result: At the same scale level QGIS just skips an entire tile level, whereas arcgis loads this level correctly. - Any other ideas? enter image description here

can you add the URL of the service so we can try it ourselves? –  iant Jul 9 at 10:29
    
Of course: Here you are: maps.wien.gv.at/basemap/1.0.0/WMTSCapabilities.xml –  root676 Jul 9 at 10:31
    
You mean you want labels for towns, cities etc (eg. "Leising") to constantly appear in a larger font when you zoom in as they did before you applied the Cubic/Average resampling? –  Joseph Jul 9 at 11:46
    
Yes, and for example the label of the road L2091 just doesn't show up. –  root676 Jul 9 at 11:57
    
Other than changing the Zoomed out option from Average and back to Nearest neighbour, I'm not sure how to maintain clarity for both the map and its corresponding labels. Perhaps others may offer advice. –  Joseph Jul 9 at 12:13

You could play around with the Resampling options in Layer Properties > Style > Resampling. I did a quick test and got the map to be a bit sharper by applying the following changes:
