it could be VRaM...who know for sure ?
but I'm more prone to think at basic computational power.
Consider that 50% less FPS is at 3440*1440. This resolution was almost non-existent when GK104 was developed (circa 2011)
Plus trying games from different years I see more or less a constant performance hit.
2008 = 95 FPS
2011 = 65-70 FPS
2012 = 60 FPS
2015 = 35 FPS
Batman AA Goty runs at 55-60FPS with everything "ON" from config menu + 4x MS + 4x SGSS + 12 Anisotropic + AO (all forced via config)
Personally I find it very enjoyable. and Gsync helps a lot in the 40 to 65 FPS range.
it 's really a Bonus compared to previous gaming
