I saw a lot of peeps having similar trouble after the nvidia 344.75 drivers dropped yesterday causing those running in SLI to have super dark shadows at night and severe ghosting of burned in textures. I did some tinkering to find a fix for both...I will test more as the texture issue can take time to happen. anyways you'll need nvidia inspector to do this.
1. Open nvidia inspector, go to settings (next to driver version) and from profiles choose far cry 3
Under sli bits copy the to sli strings and paste them on a notepad. or i can be nice give them to you here:
SLI compatibility bits (dx1x)
0x081902F5 (Far Cry 3 Blood Dragon DLC, Far Cry 3)
note: I have also tried some numbers I saw in another forum (forgot which, SLI bits was on my clipboard I had for researching fix) some people have better luck with this string instead of the (dx 1x) SLI bits above, especially if having issues with unfix-able shadows/ textures flickering that going back to the main menu and continuing won't fix. Though I found issues with trees at night near cliffs (weird setting i know right?). They seem to have a texture issue causing the leaves and some higher branches to go white or translucent and back again. A fairly minor bug to be honest.
0x080020F5
SLI compatibility bits
0x02402C05 (Far Cry 3 Blood Dragon DLC, Far Cry 3)
2. Using nvidia inspector choose far cry 4 under profiles and paste the strings in their proper SLI bits line accordingly.
3. Apply changes in upper right
4. Play Far Cry 4 in SLI at night with the proper shadows.
UPDATE: I played the game for hours with no texture ghosting. Yea!!! Also I had to use V-sync to keep it buttery smooth, off I found it stuttered but this has been true for me since far cry 2 and the move to the then first iteration of the Dunia engine.
UPDATE:I tested both SLI bits settings mentioned in step 1 for (dx 1x) and there was a very small differance for me in FPS
0x081902F5 (Far Cry 3 Blood Dragon DLC, Far Cry 3) FPS= 92-94
0x080020F5 FPS= 93-95
UPDATE:Further testing on my rig has shown the 0x080020F5 value to be less stable in some areas of the map in terms of frame rate. For me it causes FPS to dip in the 40-50's well out side the V-sync of 60hz I prefer play at on an HDTV.
UPDATE:I have now tried tried the Batman: Arkham Origins values I have seen working for some users. While they work fine as far as shadows and ghosting go I get the same spikes in the same areas I get with the 0x080020F5 value. Regardless some users claim better performance so I thought i would include them as well . Also I could not find an original poster to credit only mention of said fix. If anyone knows please post so I can give them the appropriate kudos!
SLI compatibility bits (dx1x)
0x080222F5 (Batman: Arkham Origins)
SLI compatibility bits
0x02C00045 (Batman: Arkham Origins, Batman: Arkham City, Batman: Arkham Asylum)
UPDATE: Ubisoft has dropped the 1.5.0 patch. I reinstalled the 344.75 drivers to check the results of the patch to see what if anything has been resolved. To my delight the dark shadows and ghosting glitch have been eliminated for me using the standard SLI bits provided by nvidia's 333.75 patch. I will test further to ensure ghosting does not appear after long game sessions as before. As for now I did have to drop my TXAA settings to 2x for smooth 60hz V-sync play but in the end for me that is an acceptable sacrifice for a solid game play experience. Note: all settings are maxed at 1080p, ultra, Ambient Occlusion HBAO+, TXAA 2X and with motion blur off (i hate it personally). Using two 780 GTX's SLI'd w/ i7 3930k @ 4.2ghz w/ 16g of ram with the game running off Agility 3 128gx2 SSD's raid 0.
UPDATE: Further testing has shown for me the new patch still has ghosting issues with SMAA but the shadows are still fixed as mentioned above.
UPDATE: Tested MSAA 2-8x also...no ghosting so for me at this point, only SMAA is borked. I am also not running into the blinking textures YET using MSAA settings that TXAA settings seem to have intermittently. I would be interested in other peoples experiences with the 1.5.0 patch.
