4K UHD Graphic Settings for 2 Nvidia GTX 1080's in SLI
-
Hey All,
I just spent a whole Saturday tweaking graphic settings and wanted to share my results to help those out with more high end rigs.
This was very tedious but worth it, I’m very picky about FPS drops and stuttering. For me it’s like the projector broke or the DVD started skipping around when you’re watching a movie during a good part, it just ruins the experience.
For my testing baselines I used Instant Action Fighter Sweep and Training Exercise #1 with FRAPS. The goal was 4K resolution/Max Settings at 60+ fps with minimal stuttering. I couldn’t quite get there but I tried.
1. SLI does work by default with GTX 1080’s without forcing AFR1 or AFR2. There were several posts that stated SLI doesn’t work with BMS. When I turned off SLI in the Nvidia Control Panel I took a big FPS hit (20+) and saw lots of stuttering. So if you have a 1080 SLI setup, stick with the default recommended NCP settings for SLI.
2. My first key find was setting V Sync On in the game settings and to Adaptive in the NCP. I have a 4K LG panel that tops out at 60 HZ. No matter what else I did or how high I got the frame rate in FRAPS this was what kept the motion smooth for the horizon, terrain, and other aircraft.
3. After mitigating the stuttering issues with the V sync setting, turning off the cockpit shadows and cloud reflections in the config settings gave me a nice cushion to stay above 60 fps at 4096 x 2160.
4. I was a little disappointed that I had to zero out all the sliders in the in-game graphic settings. No matter what I did I couldn’t turn up the tree density or object density and detail without noticeable stuttering.
If anybody has any other ideas, I’m open to suggestions. I think I’ve been through all the possible combinations. If anybody has any insight on the back end of things, I was wondering why DCS, IL2, and ROF run so much smoother than Falcon at 4K resolutions? Is it just the age of the graphics engine? DirectX version? Or is it just how it is coded and optimized? I don’t really have much experience with programming. A few posters mentioned that BMS bottlenecks at the CPU easily because it was coded mid 90’s. Based on my results I’ve come to the conclusion that the only way to play Falcon BMS at 4K resolutions with all the settings maxed is to wait for the next generation of graphics cards next year to try and brute force a consistent 60+ fps at 4K. Either that or try and overclock my CPU to 5.0 GHz but I’m having trouble keeping mine stable above 4.0 GHz.
Cheers,

From what i have seen and read on here, falcon just doesn’t make use of modern pc power, your spec should power this thing over 200 fps you would think… but do you really need 4k?
-
Even 2 1080s in SLI will struggle with any title at 4k, even in F4.

Drop the res, turn all the eye candy on & enjoy this thing @100fps

Do you need 4K? No, but it sure looks a lot better. Same argument could be used for so Many things. Do you need trackir? No but it sure makes a difference. Do you need mfd’s? No, but I’m not flying without them anymore. Etc etc.
I have only 1 dedicated Graphical card & I run 4k at about 30-60 fps and not everything is turned down in settings. So it should be possible. -
Hi, i have a windows 10 with i7 5820k 16gb mem gtx980ti and in 4k with all settings on trees full i have in 4096x2160 at least in aiports 50-60 fps and on air 80+.
Maybe something is wrong with your OS? or the hardware is not setup correctly.
Forget to mention that i have also another screen for export data from falcon with helios and mfd extractor. -
Hi mate I’m no expert but it looks like your nvidia settings are just for the BMS launcher not the actual 32 bit or 64 bit programs.
Maybe check that and it will help. -
I think you should be getting better performance. Even a single 1080 should crush Falcon BMS. I’m running a gtx980ti on 4K and am generally 60+ fps. This is with all sliders at their recommended levels. I do have multisampling turned only to 1 in the in-game config - turning it up past this doesn’t seem to help visual fidelity, but it does lead to dropped frames. There might be something in your Nvidia profile that’s mucking it up - try running with the default options for Nvidia.
One hidden visual item that has a lot of fps cost is focus shadows - configurable in the launcher. This leads to a big fps hit when landed / close to the ground. I find this is a much bigger hit than cockpit shadows.-Rabbit

He would have tearing all over the place at 100fps with a 60hz monitor.

Hey guys,
Just wanted to update. So it seems like I was chasing a phantom. Trying to get this sim to not stutter was akin to trying to punch a hole in water. No matter what I changed in terms of resolution, drivers, CPU clock, settings, etc. the stuttering never fully went away, only became more bearable. It was either tolerate stuttering with Vsync or tolerate tearing without it. I was also trying to hit 60+fps on the tarmac in TE#1 erroneously thinking that would be a low impact area when in fact there are large FPS drops on the ground compared to in the air.
So I have reset all my settings to default in the NCP and inspector except for V Sync Force On in the inspector settings and can max out all graphic settings with tolerable stuttering although it varies even on the same mission and graphic settings. The stuttering and overall smoothness still suck compared to ROF, IL2, DCS. I’m not complaining though, I’m more just whining because I can’t play how I want to. I’d rather spend time with this one compared to those other guys but my panel and Vsync in Falcon don’t want to play nice with each other.
I plan on investing in a G sync monitor, hopefully that finally corrects the issue. Anyone have any experience or recommendations with Gsync specifically for Falcon?

Forget to mention that i have also another screen for export data from falcon with helios and mfd extractor.I had pretty much the same with a 2600K and 970GTX. (along with 4 other screens for display extraction off a GTX750 - which does nothing GPU-wise).
now with a single 1080 I get over 80 at all times

Another successful cross-fire/SLI user story.

Hey guys, I assume this is a dead thread but just in case somebody actually does read this. I did finally solve the problem and it had nothing to do with Nvidia settings or SLI which worked splendidly once I figured out the problem. The problem was my CPU power settings that had reset to default in one of my many reinstalls of Windows. DUHHHH!!! Once the CPU was properly set to max performance and I learned to unpark my cores, all the stuttering issues went away and I could enjoy 60fps smoothly with everything maxed in 4K. I can even crank up the supersampling and AA in Nvidia Inspector and it looks phenomenal. You cannot see any pixels or jaggies. CPU was definitely the bottleneck. Without V sync and with both cards cranking I could break 100 fps easily. I usually play on my big screen still, but when I’ve played on a smaller monitor that goes to 165Hz the difference in smoothness is noticeable especially when panning around the cockpit with TrackIR. Best guess it that a single 1070/1060 will run everything maxed in 4K60 with at least x2 AA when properly configured in the driver with a fast CPU with good single thread performance. Happy flyin’

Glad you sorted it out finally. Most of the times the biggest problems have the stupidest simplest solution…
Well I believe with just one GPU u will be the same… so in this sharing community… the one that has two should give one to the other… :lol:
I’m open for receiving… :rofl: -
I constantly have about 80-120 FPS in the 3d world under fire and low flying, and I have a stock 1050 with an i5.
