@master2g "Vaseline on my screen" LOLOL. Yup, I never could figure out why NFS2015 was designed to be so blurry!
Being able to make adjustments on the fly is a great feature. I'm not sure of the current state of GEMfx because I haven't messed with it in probably a year. At the time, you couldn't make adjustments on the fly because it had to hook the game on startup. The games I adjusted with it primarily was Rome Total War 2, Batman Arkham Asylum, Batman Arkham City, and Batman Arkham Origins. I tweaked the Batman games shortly after they released the remastered versions for the consoles, and I was curious to see what improvements I could get by modding the PC versions... It took hours (I'm sure you can relate) but I'm happy to say they look incredible. By modifying the texture fidelity in the config files, maxing out settings in-game, using Nvidia control panel, and tweaking color and effects using GEMfx, I was able to duplicate the visual quality of the remasters. The only things still lacking were some of the effects that simply weren't available in the games 8- 10 years ago.
Unfortunately my GTX690 is unable to take any kind of a performance hit trying to run Payback (there's no SLI profile, which I could greatly use). I'm averaging around 34 FPS, which is playable for me, but in the tunnels it tanks to the low 20s and I usually crash because of it.
Anyways, for everyone else, sorry to get off-topic. I'll post some car pics when I'm home and have the time...
