Getting tired of fighting this problem . Bought a 980ti SC and it can't max out BL2 w/PhysX on high , so I added a 760 . Any time I get heavy particle usage with PhysX on high the game will freeze up and then crash the pc . Set PhysX on med or low , no problem (except for Opportunity) . Was playing last night , just entered the Beatdown & started fighting . When one of the enemy use an explosive shotgun the fps tanks , gpu memory goes nuts & freeze up & crash followed . The screens went black , then the far left one had colored lines in a bar appear at the top of it . The 980ti's fans went nuts at the same time also & were screaming (maybe coil wine ?) . Ctrl-alt-del out was no help either . rebooted pc & it was sluggish as heck , having a NVidia driver crash in system viewer . When looking in the event viewer nvlddmkm is showing up way too many times (count is over 9,000) . Before last night's latest episode I downloaded the DX9 final & reran it (was missing some files) . Then cleared out the driver & files and did a clean install of 355.82 driver . Didn't help . I only get the hard crashes in BL2 , none in my other games . But I do get nvlddmkm in the event viewer when playing other games . What the heck is going on here ?

I'll try it a little later . I just got of some solo BL2 play w/PhysX at medium . Had 15 instances of nvlddmkm in the event viewer while playing .

Talked to Lee in tech support , he doesn't think it needs an rma . He tells me to "ignore the TDR instances" .  Blames everything on the game (partially correct , still shouldn't crash the pc) . I tried playing again w/PhysX on high but moved the PhysX load to the 980ti , no crash or TDRs ! Now when I switch back to using the 760 the TDRs and crashing returns . Curious when the crash happens on the Logitech keyboard display it's the 760 that has the issues only . Temp goes to zero and it's fan goes wide open . I also tried 3 of the Arkham titles on just the 980ti (AC , origins & AK) and they played it fine , except for AK . Minimum fps were a little lower & I noticed when driving the batmobile the center screen would tear occasionally (too much even for it maybe ? ) . Guess I'll just run PhysX on the 980ti when playing BL2 from now on (and test the 760 by itself) . Why do I always get the weird problems ??

I've uninstalled the driver & used DDU & reinstalled 355.52 . Seems to work best with the Surround setup . I'm about ready to dump it and move on to a single higher resolution monitor (1440 at least ) larger than 23" of course . Wife suggested I spend the money on her , I told her that was a poor return on my investment . I woke up on the floor again.... But seriously , lack of sli and multi-monitor support is getting to be a big headache with no end in site . MGSV , shows 5760x1080 in graphics but only gives you a single monitor to use . Arkham Knight gave up trying to get sli to work and other AAA titles dropping w/no sli support .

Well I ordered a 4k monitor , it should be here on Monday . I'll play with the drivers then .  I played some bl2 tonite , had no crashing w/physx on medium , just low fps when the particles start flying . Still seems strange for it to drop that low (mid to low30 fps) . Also still getting alot of driver errors in the event viewer . Just gotta wait until Monday . Going to be a  looong wait !

Ok , so I decided to play with the drivers before my new monitor arrives . I uninstalled 355.82 w/ DDU and installed 359.00 driver . All my event errors are now gone & haven't had any crashes w/PhysX on high ! Hurray for me  ! I'll use this driver on my 960 sli rig when I move the surround to it tomorrow .
 Edit : the 359.00 driver causes Arkham Knight to crash my system . So I guess I have to play the driver swap game depending on the game I want to play...just great

Better than not being able to play at all.

Driver 361.75 seems to have took care of it (finally) . But now I have a single monitor on it (4k to boot) . Oh well , time to test it on my other rig .

Yea , I ran into another issue . I had to send my new 4k monitor back today ! Only had it 2 days...... Wouldn't always respond to the power switch & would lose video when running a long benchmark or come out of display sleep . Only way to get it back was reboot or pull the hdmi cable & reinstall . Fortunately Monoprice made the RMA painless . Once they saw it was shipped back w/their prepaid label they started shipping me a replacement . They said I should have it by Friday . Now the waiting begins , again ...
