Another driver has rolled out, will install and update the results. Fingers crossed sli and DX11 can get along.

[Dunark]

I've been running MWO in DX11 for a while, but SLI never did seem to work in this game.

I just updated my Nvidia drivers to 344.65 and DX11 stopped working correctly in MWO . . . the brightness of the image "pulsates" while playing, and sometimes I can still see a shadow image of the mech bay when I'm in a game (and vice versa.) No problems noted yet with other games and applications, problem seems to be specific to MWO and DX11.

Dropping back to DX9 in settings made MWO playable again.

System:

Alienware R4
3960x processor, 32 GB RAM
2 x 680GTX cards
x64 Windows 8.1

[Obi1Raven]

Same, I have reverted to DX9..

[DarthPeanut]

Just installed it but have not had a chance to try it.

In the release notes it does say under the added or updated application profiles MechWarrior Online... so maybe some improvement.

I am still in DX9 as well... there where bugs with DX11.

It seems like an awful lot of people do not pay attention or search the forums.

To avoid confusion: the SLI profile was added a couple of driver releases ago when Nvidia released the new base 344.xx driver. The last 2 releases were game ready drivers for major game launches (new CoD, new AC). There is nothing significant here for MWO players that wasn't in the earlier 344.xx releases.

[DarthPeanut]

I was aware of the previous posts about this. My post was in follow up to them... hoping for an update to the profile since it was listed under the category for "added or updated application profiles" in the release notes.

[CmdrPoopyPants]

I can confirm that 344.65 seems to break MWO (at least in DX11)

Do we have a "last good version" for DX11? I know my 340.52 seemed to be working well.. I only updated because the nVidia game experience thing popped up saying updates for the driver were available. ... now I'm remembering why I don't update drivers all that often, and laugh when game makers say "try updating to the latest drivers". What a load of ****.

I have found dx11 works fine on my machine with this driver and MWO. i don't have sli. I also perform clean installs for driver updates. http://pcpartpicker.com/b/mdsYcf

Why on Earth would you guys be trying to playin MWO in DX11? It's just the same game with lower, more variable framerates.

Anyways, how does SLI actually seem to perform? Is the scaling good when enabled? Is there noticeable stutter?

Weird artifacts, ghosting, and overlay issues should be resolvable through the following method:

Access NVIDIA Control Panel
Manage 3D Settings
Program Settings
Add or access the profile for MWOclient.exe (not mechwarrioronline.exe)
Set your SLI Rendering Mode to 'Force alternate frame rendering mode 1'

Feel free to report back here with any changes you see

SLI rendering mode isn't showing up. Perhaps my GTX 745 isn't classy enough.

No more flickering in the mechlab with this, and no flickering water, so far! Generally feels a little smoother too.

This is with DX11 SLI latest (344.75) drivers GTX 970s

Thanks!

Artifacts, ghosting, and overlay issues seem to be resolved with A.G.'s suggestions.

Running 1920x1080, all other settings maxed; FPS in Caustic test map averages 130-140, occasionally tops 200(!). FPS in a real game on Terra Therma was averaging in the high 80s, but dipped into the high 40s when a lot was going on.

No indication that SLI was active.

TY guys! I have been having issues for awhile, but now not only are my issues gone I'm in SLI and DX11.

Fixed the ghosting, but I'm getting some significant frame rate degradation on some maps (so far, Caustic and Frozen City Night dipping as low as 31fps for a few moments) that I didn't get before I updated the driver. I guess I'll just stick with DX9 for now.

[Durant Carlyle]

There's another new driver out, folks. So much fun upgrading every few days!

[Raidflex]

Anyone have a chance to try the new driver (344.75) released yesterday? I am wondering if the erratic frame-rates have been fixed while running SLI.

[Alexander Garden]

Looks like 344.75 hasn't made any difference, but I'd be interested to know if anyone sees different behaviour while running it.

[CHH Badkarma]

Out of curiosity, since it was mentioned that PGI was working with Nvidia to iron out the kinks, have they given you folks any idea on their progress or an ETA for a more optimised driver?

[Raidflex]

I did get a chance to test SLI last night with driver 344.75. I found that the erratic FPS although still present, was less profound. Also using the settings Alex posted above did help eliminate most of the flicker issues, although sometimes during game play the brightness would dim and come back. Overall I felt like SLI was actually helping this time, instead of dealing with huge FPS fluctuations that made it unplayable in the past.
