With the Urban Terror game, there is a jump in the frame-rate from 2010Q4 to 2011Q1, but then a small drop before the 2011Q3 release but still an improvement over where it was in 2010. In the fourth quarter of 2011 there was no Ironlake performance improvements touching Urban Terror.
The Lightsmark frame-rate did go up over 2011 for the previous-generation Intel graphics, but still quite slow compared to Sandy Bridge.
Nexuiz went from being an unplayable mess in late 2010 and early 2011 to now being better off since the third quarter of 2011. However, the frame-rates with the Intel Core i3 330M CPU still were not good enough at 1280 x 1024 for a playable experience.
