GTA 5 - Poor SLI Scaling

String said:
Unfortunately, I'm sinking below 60 regularly and averaging around 70.

There's definitely something not right, I just can't think what it is. :confused:

Do the following shadows to high advanced shadows to off and msaa off you should get 80-150 quite easily if your still stuck under 60 we can look further

Makes no difference. :(



Here's single GPU forced in NCP...

And here's SLI...

As you can see, single GPU utilisation is 90%+, but SLI utilisation is in the 60s and I've gained 9 frames.

Something definitely not right.
 
Try the following:
1. Remove that FPS locking crap you got running :p
retest

if not different
Reset all NV 3D settings in case you left somthing on in general settings, maybe 4x MFAA or High Qaulity AF etc.

2. Re-download the driver
3. Do a NVidia Custom Clean Install
4. set everything on GTA to Say High (not very high or ultra)
5. GTA IN Direct X 11 mode?

any difference?
5. CHeck your SLI bridge connector is nicely secure
6. check the PCI-E lanes are correct 4970k are 16x and 8X?

Tried all that mate, and no change.

I even switched to a 1080p non Gsync monitor but the scaling is still awful. So I can rule out issues with the Swift.

Running out of ideas here.

If I want to roll back the driver, can I just run the installer and choose clean install, or would I have to DDU first?
 
ive notcied this too

980 SLI ROG swift 5930k @ 4.5

settings maxed except msaa off and my fps in the 60-80s with GU usage in the 60% range

v-sync off and refresh set to 119hz

think its a driver bug

That's pretty much carbon copy of my experience.

I'll roll the driver back and see if it makes any difference.

I never use DDU its pointless in most instances, if you do a Clean Install with NV you will be fine

People just use DDU because others recommended it & they only recommended it because someone else does. They only recommended it because once a friend of a friend had a issue where it was fixed with DDU

99.9% time its a waste of time & can cause more issue than good

just for reference this was all maxed including MSAA

you wont be able to stream it as its 50mbps video but if you jump through Afterburner most of time my SLI scaling is 70+ lot of the time 80-90% @ 1440p wiuth rog swift with 2x 980s ref & shadowplaying :p

When you say scaling is broken are you seeing equal usage across the two cards in afterburner or similar?

My 970s seem to run at 60-70% utilisation but it's split identically between the two cards. I assumed this just meant something other than the GPU was bottle necking? Bad scaling examples I've seen before have always been one card working very hard and one not doing much?

I can get mine to max out if I have all the advanced graphics options on but otherwise can't.

Will keep an eye on thread but not sure it's a bug...
 
It's only 'bad' scaling if it's not maxing out both cards - if it needs to. If people are playing this locked at 60fps for example, which I'm guessing many will, then two decent cards like 970's in SLI pumping away at 70% usage each, sounds just as it should be to me if a steady 60fps is all you want to hit.

Edit - just re-read your first post, you're running at 144hz, sorry. Hmmm, not sure then, perhaps a bottleneck of some sort. I'm expecting delivery of the game on DVD today (a first for years!) and will do some extensive tinkering and testing with this one. I run 780Ti SLI and a 2600k at 4.5ghz, and a Rog Swift - so a fairly similar set up to the OP!

Wunkley, thanks I appreciate your input.

To recap:

It's maybe not bad scaling as such, I mean the cards have a pretty equal percentage whether it be 99% or 60%. The only way I can get the cards to work 99% is to enable MSAA at 8x. However, this gives a similar FPS to the cards working at 60% with MSAA off so it's pointless.

It's a bottleneck of some kind, but I seriously don't think it's hardware. A guy with pretty much the exact same spec as me has the exact same issue.

I'm starting to think it may be memory related. :confused:

** EDIT **


Here's the graphics settings :

I guess the only thing to do now is wait it out for new drivers or a game patch and see if it's sorted. I wouldn't go changing things yet as it might not be something you can fix.
 
These sort of issues are exactly why I went with a Titan X over 980 sli (which I was going to do). Can only imagine this is sli profile related.
 
Yep and I was thinking yesterday about going 980 SLI instead of my Titan X as I'd initially heard good things about multi GPU scaling and performance, seems there's issues on both sides with CF as well.
 
I have GTX670 SLI and mine do not seem to be getting stressed at all. I do have vsync on in nvidia control panel but they never go above about 70% usage. This is with very high settings, AA off in 1440p on an i5 760@4ghz & 8gb ram.

FPS does dip below 60fps but even then the GPU usage reported by riva tuner is below 50% sometimes. How about making a game that is compatible with SLI and Crossfire. Crysis 3 I get constant high FPS because my GPUs are working their balls off at 99 or 100%

Do you have a link for the profile?

Sorry for the belated reply I've been a bit busy...

No I don't sorry. I just put "dying light SLI flickering" into a famous search engine and found a link that showed how to edit the profile and what to change it to..

I could swear that I was getting better FPS before GTAV updated itself the other day.
