I am running 2 sapphire 7870 oc Ghz edition gpu's in crossfire, and I have been able to play most game titles at highest settings with little frame rate issues---I just downloaded Metro Last LIght off of steam, and i played through the 1st 3 check points on all high settings with little frame rate/stickiness issues, until i reached the point where everything is dark, there are a group of enemies in a room and everything is lit by lantern light, now the game is not playable at all, game is jumiping around, gets worse with multiple enemies firing at me etc. I have tried adjusting game settings down, no luck---tried adjusting resoultion down with no luck; now i am at all settings all the way down, all a/a v sync etc off, nothing--still not playable--rest of system, amd 8350 oc 4.6 ghz, xspc watercooling, asrock exreme9 mobo---no issues on any other games, and i knew this was a graphics intense title, but geeze, not being able to play it at all???wtf??? any ideas??? also, i have 2 asus mars dual gpu's on order, going to pull the 7870's and install the 2 mars in sli----will this help or am i having other issues elsewhere in my system? Kind of tricky because i can play crysis 3 on ultra with little issues at all, tomb raider, no prob, bioshock, again high/ultra settings no issues with my 7870s'---1 more thing--i am playing on a 52" plasma tv, via hdmi, and it has a 60hz refresh rate---also it is a 780p tv---i know not the best way to go here, but it has not effected any of my other gameplay until now---but obviously i am not even getting 60 fps on my 60 hz in metro if it is completely un-playable after the 3rd-4th check points--i mean its skipping so bad i can shoot my gun and there is a 2-3 second delay before it fires---

Well, the box isnt checked at all, so i don't think so unless it can be turned on or off somewhere else--I also just finished running the metro benchmark utility, and my framerates look decent---on all ultra, everything on i averaged 92 fps, high was around 136. but there was one frame that had a low of 10----now the benchmarking scene is different than the scene i am having issues with, it is better lit, but it does have alot of fighting. then again, i didnt have issues on the 1st 3 scenes that were better lit, even when fighting, its this low lit scene that is giving me issues---i am beginiing to wonder if it is even a gpu issue and maybe a game download issue? idk what do you think----

It seems as Physx is not checked in the graphics section, is there another place it could be turned on?

well problem solved---It was definitely something with the 7870's because i just installed 2 ASUS ROG Mars 760 in QuadFire and they crush this game with all settings ultra and maxed out---but then again for 1300.00 they should right???? Anyway---thanks for all of the help everyone!! Happy Gaming <~~~~ Suferbus :)
