You may have worse performance in fullscreen because vsynk works only in fullscreen IIRC.

Try disabling vsynk both in game AND in drivers. If it helps consider enabling triple buffering if you need vsynk.

Same may be the case with FSAA. Try disabling it for a test.

Check that your Windows powersaving options are disabled completely and nothing runs in background (try Gamebooster). My defrag software somehow did not recognized CloD as a running application in fullscreen and started to defrag before it was disabled by Gamebooster. Same can happen with indexing services, autoupdates, etc.
