Most recent: Download Center
edit: no idea why my direct link doesn't work. Just go to downloadcenter and download 22.214.171.124.2761.
And it makes a big difference between 2361 and 2342. 2342 was based on 15.21 and 2361 was the first 15.22 release with performance improvements in general for the HD3000. And yes 2669, 2696 and all 15.28 drivers have a performance bug in HL2, don't use it.
