Sorry about the multiple posts. The forum was a bit dodgy when I tried posting. Needless to say, 15.6 works like a charm. I just wanted to say thanks Unwinder. The compatibility fix you used works for BF2 also. Thanks again !
Go to the Target Adapter Section, click the Customize button, Select the Hardware Monitoring tab, Click setup, pick what you want to show and set to OSD. Turn on the monitor and close RT. Naviagte to Start, Programs, Riva Tuner, select RT Statistics Server. RTSS has to be on to see the OSD ingame. Now play a game. I have found it to work with HL2, CoD, BF42, BF2, Brothers in Arms and Far Cry. Pretty sweet ! It's nice to be able to monitor GPU temps while gaming.
