Low FPS with GTX970


leos

Recommended Posts

Hello everyone my dcs is runing low fps in my pc I already tried to set everything at low and still the same thing like I was running at high.

 

AMD FX-8120

8gb

GTX970

SSD 60gb

HDD 2tb

 

With everything on high I got a max of 18fps and the lowest was 7fps

 

At low the max was 40fps.

 

Always with vsync off.

Set your MSAA to 4X. Set your Resolution of Cockpit Display to 512 or 1024, but you don't need every frame.

with that MSAA Level + Texture Levels, You're breaking past the 3.5 GB of VRAM into the .5GB Partition, which slows things down to a crawl..

The low frame rate could be from your CPU. DCS like strong single core performance which favors Intel. EDGE will probably help though. Otherwise the 970 is a very strong card, the CPU is probably your bottleneck.

 

As for the settings

Depending on the size of your screen you should back off from the 16q antialiasing. 8x should be plenty unless you have a huge HDTV or something.

 

The "every frame" setting for the cockpit displays, I think is there for dual cards or I only see a benefit when running both GPUs. Try setting it to just 1024

 

IMO the best performance saving comes from turning down Visibility Range and the difference in quality is acceptable.

The 970 has been a great upgrade for me, coming from a GTX 760.

 

There are a few setting tweaks that I would recommend testing, such as turning down AA to 8x or lower,turning down shadow quality, reducing civ traffic and the "every frame" setting for cockpit displays.

 

I plan on upgrading to 6gb card myself, the only performance issues I encounter are slow downs usually caused by a lot of units on screen at once.

 

Tweaking is necessary to achieve the optimal performance/quality you are used to. Sometimes however performance is compromised another factor, I hope you are able get it pinned down. Like everyone says, DCS 2.0 is around the corner.

Turn down the AA, turn off HDR, and crank down those sliders on the right. I'm not surprised you're having FPS issues with the settings maxed out.

I skipped the GTX 970 when I built my new rig (money issue). I also have the GTX760 and wonder what the benefit would be. Could you become more specific. Sorry for using this thread for my purposes ;)

Thanks,

Turn TSSAA off.

 

What motherboard do you have?

 

Try shutting off 4 cores and overclocking as far as you can go on the remaining 4. Try to stay 1.488V or less while under load.

 

 

I have a Sabertooth 990.

Almost certain about my cpu being a bootleneck, but I think it's strange because when I run the Witcher 3 all the settings are at ultra and run at 50fps(this gave me the light of my cpu being the bottleneck) stable and at DCS I have this issue.

I hope that the DCS 2.0 fix some issues about low fps that happend in DCS. Let's wait and see what will be.

I run an i5 with a GTX660 and keep my frames between 45-70.

 

Biggest things have already been mentioned: reduce MSAA (that's a load on both GPU and VRAM), uncheck TSSAA, and set your cockpit display res to 512 (and not every frame). Just from that alone you should see a significant increase in frames.

 

You may want to decrease your clutter and trees numbers as well if you need to get more frames. The clutter also sucks up your VRAM, and the trees increase the objects rendered (which with DX9 has an effect on the CPU). I use 300 for clutter and 6000 (1 nautical mile) for trees, and works just fine; you would probably have no trouble if you doubled that or more. Keep the preload radius at max; that's one time where a larger number means better performance.

Exactly, He's eating up VRAM to the point where it starts using the slower .5GB Partition, which amplifies any FPS Issues.

this is the age old YOU CANNOT COMPARE ONE GAME'S PERFORMANCE TO ANOTHER SIMULATOR's... its the same as comparing chalk to cheese or apples to oranges (I don't mean to shout, I'm just going for clarity)

 

With your PC's specs you need to state (along with that which has been listed) the mobo (even though I see it has been listed later in the thread) and operating system being used and where your DCS installation has been directed to.

 

The hard part is, some systems are better than others... and even though the current engine is aged - it will still make some systems go wobbly at the knees and cry if the settings are fully maxed out

 

I have a reasonably high end system and can't run "maxed out"

 

You need to "experiment a bit" with your game settings and system settings - you know "tweak", and then bearing in mind, there are some anomalies, which are present (and acknowledged) which exist with regard the airports and towns

the cpu is absolutely your bottleneck for dcs. This can change when dcs 2.0 comes out or buy a badass cpu. Maybe a tip is http://store.steampowered.com/app/384300/

 

I use it too. My minimum framerate are 10 fps more then before. The most people don't believe this. But if you tried and not happy. You can get an steam refund. So i recommend you try it, if you don't like it. Refund..

does nothing in reality... try to relax the pushing and advertising of it (keep in mind, that if your hard earned is in their account - they're making interest off that, so even when refunded, they are still making something from the transaction. Its not the "fix all" panacea which some claim)

FX8120 chips have a bunch of issues with internal cache and scheduler,

 

you'd be better off putting that chip in a box as a backup and getting a FX8320 or better

 

but that is not the source of your problem, as I have a 8120 in another system driving 2 AMD 7950s in Xfire perfectly fine and DCS has Decent FPS (Xfire disabled),

 

Your issue is your overzealous settings.

ie MSAA 16xQ, which is actually MSAA 32x....

 

that setting alone is numing your FPS and sucking up all your VRAM, drop to 4x,, and move up a notch at a time until you start to get FPS lower than what you want.

 

 

 

as for that steam app for performance, its a placebo, those "tweaks" are already part of winsows and usable without paying for that software, if GUI friendlyness is a issue or ease of use, there are also free programs that do the same thing.

 

changing process priorities and affinities and closing off services they deem expendable is easy enough to do on your own, just dont come here complaining about issues when it decides something dcs uses as a service is expendable and screws everything up.

I set these way and worked well sometimes still dropping fps but was in a first try I will try some other changes latter.

 

I'm trying to not lose my head with these thing but if the game runs ok it's fine.

 

Like the guy said before DCS 2 is almost here, and I want to do some upgrades on my pc and than will see.

 

Latter I do some other changes an see how will work and post here.

 

Thanks a lot guys.

I am running everything maxed with my GTX 970 and it runs more than fine (90 fps is no exeption depending on the situation). I have a i5 4690K and would rather look at your CPU than graphics card.

Also I have no problem with running out of vram. Never had the slowdown of the last 0.5 gb ram.

 

Running at 1920x1080 btw. But I even tried 4k dsr, and it was still playable.

Honestly you are right about skipping the 970, I plan on using evgas step up program to get a 980 Ti 6gb card.

The GTX 970 is easily capable of playing this game on max. I can't say what your problem is, but providing it's OK ( check it with MSI Afterburner ), it ain't the graphics card.

I agree with you Holbeach ... I've very pleased with my EVGA GTX 970 SSC performance compared to my previous GTX 660.

Maxing Textures, and Putting MSAA 16xQ, change it to 16x or 8x,

 

the Q settings are CSAA, which enhances the applications built in msaa,

 

your clogging your GPU, and pushing VRAM into the last .5 partition which kills your FPS even more.

 

Set AA to Application controlled in NVCP, then 4x i DCS, and work your way up, just dont use the Q modes.

 

 

add all that to the fact that your bus is limited to PCIe2.0 16 Lanes.

 

So, Reduce MSAA, turn TSAA off, MFDs to non every frame setting.

I will add that I just received my 970 today, with similar settings to the OP's latest settings, except shadows on medium, cockpit displays at 512, and MSAA at 4, I'm averaging 55FPS in the MiG-21bis during takeoff.....with 3 monitors.

 

Keep dropping that MSAA, it will help a lot, but that AMD along with it's relatively low clock speed will hold you back some.

 

Also drop the pre-load radius as low as it goes, you're just increasing your load time.
