Ive been using this raptr replay for a long time and would hate to have to go back to fraps.
after the last update of Elder Scrolls Online raptr replay records all choppy now, i have an over clocked video cards in crossfire that were recording perfect before the last update. something may be messed up with raptr not being up to date maybe and needs an update.
Try turning the game into DX9 not 11. I have to use DX9 for 3D now. DX11 is only really more efficient but seems to have an effect on things like 3D rendering and recording etc. Plays nicer but not for 3rd party software.
See if it helps...
