S.T.A.L.K.E.R Lost Alpha performance test on 5.5 years old single Ge Force GTS 450 at 1920x1080p. Game is updated to latest version 1.3003. Keep in mind that i have 2-3 fps more without Bandicam recording. Game is using 97 to 99 percent GPU core and 1015 MB VRAM, checked in MSI Afterburner......So as you can see Fermi gpu still kicking very good. Very cheap gpu it was cost me 150 eur in 2010 year, well worth it.
