DX 9 SLI going to work on the 25th?

mrvuk

Greetings,

I've posted before on the bug issue of DX9 and SLI not working. I haven't seen a reply from any devs that they know about the problem or if it will even be fixed before open beta. Any news on this?

Thanks

Hi, what graphics cards are you using?

mrvuk

2 Nvidia Geforce 580's SLI. I have latest updated driver with the Neverwinter profile. SLI works for all my other supported games (tombraider, metro2033, etc...) I also know the workaround if you edit the neverwinter profile to the correct directory. I was just hopeing they would confirm a fix before the 25th.

It doesn't work in DX11 either.

You can select it, and it will show that you are using two GPU's, but there is no FPS gain. I actually lost a couple FPS by using SLI. I have two SLI machines and both experience the same issue with this game (while SLI works correctly in other games).

I don't know if this is something NVidia needs to optimize or if the game needs to be directly coded to handle SLI better.

I use 2x GTX 470's on one machine and 2x GTX 580's on the other.

The path in the profile does look like this: Neverwinter/playtest/gameclient.exe
The problem - I actually do not have a folder called "playtest" in my Neverwinter main folder.
The way I got it working is pretty simple though - I just added the gameclient.exe (found in your Neverwinter/live folder) via Nvidia Inspector to the recently added Dungeons&Dragons Neverwinter profile. Before you can do this you have to delete another profile (in the list containing all profiles in NV Inspector) called "gameclient" though as adding the Neverwinter gameclient.exe will not work until the other profile is being deleted.

Thats been on the forum for awhile. I haven't seen any reply or even a hint that Dev's know about the issue. If you enable SLI indicator in the nvidia control pannel, it should show a green bar on the left of any game that supports SLI. The green box grows taller as SLI GPU scaling increases, compared to a single GPU.

Did you try to manually select AFR2 via NVIDIA control panel? This worked well for me in beta 3 with dx9 and dx11, and in beta 4 with dx9 as well. I have a GTX 690. GPU usage was nicely even between the 2 as well, according to EVGA Precision.

EDIT: Actually in beta 4 I had to correct the gameclient.exe path in the profile via NVIDIA Inspector.

AFR2 ? (alternate frame rate 2)
Yep, I know how to get it working correctly. I was hopeing that the gameclient.exe path will be fixed before the 25th so people don't have to go into the profile editor. I wonder if that would be an Nvidia update instead of a Neverwinter patch?

Just out of couriosity, are your cards hardware SLI, or software SLI? Just had one of my vid cards die on me last wednesday ( 2 HD 4870's ), and went to looking for replacements. While researching for best bang for least buck, noticed that alot of the newer AMD and Nvidea cards do not have the bridge connecters on them any more. They are useing the PCIE interface for the bridgeing function on some versions of the cards. It is a possibility, and only a highly speculative one at that on my part, that the software type cards may run into more issuse than the hard wired bridged ones. Depending on how many cards you have pluged into your MB, your PCI buss could be very busy. That usualy leads to missed or messed up communication somewhere at some point in time. any way just a thought on possible source of SLI/Crossfire issues.

My SLI is hardware (the little attachment ribbon between the 2 cards) I know it works correctly because I get 60 FPS in the latest tombraider benchmark and the SLI indicator shows when I enable it. The SLI bridge you're talking about should come with the motherboard not the videocard? I was unaware that you could use software to link 2 cards SLI. I haven't upgraded my MB or Video cards in a while so, I wouldn't know for sure.

I'm also using hardware SLI on my two sets.

I also tested alternate frame rendering 1 & 2 during the beta weekends. While SLI was working (both cards were sitting around 20% usage) - the FPS did not increase over what I was receiving with a single card (at 50% usage). VSync was disabled (In the menu, I could easily push 300+ FPS).

Sjiro , did you go into the profile editor and check to see if gameclient.exe is running in correct directory? It should be neverwinter/liive not neverwinter/playtest. I put a quote up by oldsnakemgs that explains why the SLI profile is messed up.

sjiro

I added the gameclient.exe myself when selecting AFR2. I didn't adjust the SLI profile though, that may make a difference. Thanks for the tip! I will adjust it the next time I'm in game.

[EDIT]
After editing the profile:
In the launcher, at least, it seems to be working in DX9. Not in DX11 though, which was expected.
Let's hope there is a noticeable improvement in the actual game!~

Thanks again!

I guess we'll see if it's fixed on the 25th

I just read on another post that the new Nvidia beta driver has an updated Neverwinter profile that should work. Nvidia Beta driver with updated Neverwinter SLI profile

That profile also works with DX11. Just tested.

Yep, I just saw that.

I went into a profile editor to see what they changed. They just added a /neverwinter/live directory on top of the /neverwinter/test , lol. Better then having to tell people how to do it over the support phone line I guess. I cant wait for the 25th.
