FLIR - FPS killer

[ody81]

So has this issue been reported to the devs?

[Gary]

Good question...

 

Is there a list of acknowledged bug / issues ED have recorded anywhere?

 

It would be good if they did have as an easy reference before others post issues already logged.

Hi, I think that this behavior is normal on low-mid end GPUs. I have 750ti and had this drops even in 1.2. I assume that engine needs to render another "pixels" on MFCD and this consumes lot of GPU performance. My friend have GTX 970 and on Full HD and 1024 MFCD res he have drops too, but very small.

 

Gary:

yeah your NTB have i5 but with M or U letter after numerical description of model like 5200U which means that this CPUs are crippled because of ntb heating, power cunsumption etc. So they are not powerfull as normal desktop models

 

And same is aplied to your GPU, again M means mobile, so this GPU is much less powerfull than equivalent desktop model and most close is HD6670 which is old "rebranded" and little bit optimalized HD4670 with more RAM so no woonder that your rig "sucks" at DCS

Thanks. I've been around computers a very long time and I'm well aware of my current hardware and its limitations.

 

However, my reply was not specific necessarily in relation to my system - just an observation that discounting the validity of an observation from a laptop user was mis-guided.

 

I've seen a number of posts from laptop users on here.

 

Frankly, FLIR fps drops aside, my fps and in game performance is exceptionally good. I've not used the frame counter because frankly I haven't felt the need to. I was under the impression anything over 40ish frames is fluid - and mine certainly is very fluid.

 

I turn a couple of things down (water on medium - tree shadows off - MSAA and AF both x4) and everything else is maxed.

 

I've been using flight sims for the last 30 years...so I know how poor fps can kill the experience.

 

Mine is very good with 1.5

 

Kind Regards,

 

Gary

The frame drop in 1.2 was minimal, barely noticeable and more in line performance wise with the rest of the sim.

 

The frame drop in 1.5 is so striking and renders the A-10 especially unusable, it's gotta be a problem with optimization or a bug. It doesn't seem right at all given the performance increase in all other areas.

This. The frame drop pre-1.5 was negligible for me, now it's 30-40% of my FPS. Much worse if I have FLIR on TGP and AGM-65Ds up at the same time.

[Dutch727]

There's also quite a drop in FPS using the SU-25T Shkval.

 

I concur the A-10C can hardly be used if I turn on any FLIR.

[alaryk]

A10 C unplayable

 

Feeling the Same...

A10 is almost umplayable for me dropping from 60 fps to 15-20, even less sometime...

I have almost the same Pb with ka 50....

 

Hope they will find a fix soon...

[Toxic]

Agreed. FLIR is FPS killer. Down from 60fps to 20-15fps

I am not seeing this issue on my end. Perhaps share your graphics settings, just a screenshot and I can try and use the same settings to compare.

 

Also include your specs, and make sure your graphics drivers are up to date please.

Alrighty, I'll post my specs again.

 

i5 4670k, nvidia 760gtx, 16 gb ram, trackir 5, saitek x52, Windows 10.

 

Running at 1920x1080, everything on high, flat shadows are off, vsync on (and adaptive on in the nvidia control panel), panels at 512 (not every frame). I get a constant 60fps aside from the TGP, MAV and Shkval (Shkval is only affected on Vhkr launch).

 

I've turned absolutely everything to low and turned on flat shadows and get the same issue, TGP with FLIR and/or MAV, or launching with the Shkval devestates the framerate.

 

Alt-Enter into true fullscreen doesn't make a difference.

I recorded a track in the A-10 as well, think the link is on page 2 or 3 here.

 

Seems you either have the problem or you don't. All my drivers are up to date, my system normally kicks arse. You <could> say the 760gtx isn't a great card to be using BUT I am only running at 1920x1080 and they're more than capable of running anything at that res. Plus there's guys here with better specced cards than mine with the same issue.

[billeinstein]

How about the aspect ratio? If your resolution is 1920x1080, you must set the ratio to 16:9 or 1.7...78. The setting of 1.6 will kill the FPS.

I added a video that show the exact issue that is being reported in the Thread, before anyone asks my specs are below, the video was recorded with crossfire enabled both GPU's were at 1120GHz. I started the video at the main menu started a non busy single aircraft mission, 0 triggers, 0 movement at airport other then the A-10c on runway. Once the mission started I panned around and you can see just moving my head caused a drop in FPS. engaged the TGP and started the Mav Timer. Also I'm not moving, flying or otherwise causing reloading of the preload area.

 

Watch the Dips in FPS while I look around the cockpit and Right to Left. TrackIR is off and I'm using the Keyboard.

 

With Only TGP On:

Boat Switch Center: Normal 60 FPS what I started with at the beginning of Mission.

4 Min 33 Sec: Boat Switch Moved Aft: drop to around 20 FPS

4 Min 43 Sec: Boat Switch Forward: Drop to around 20 FPS

 

Repeated above

 

TGP and Mav On:

5 Min 26 Sec: Mav on FPS Dropped to around 20 FPS TGP Boat Switch Center

5 Min 48 Sec: Mav off TGP Aft Drop to around 20 FPS

5 Min 51 Sec: Mav on TGP Aft Drop to around 15 FPS

 

 

Please Make sure your Quality Level is Set to 1080P Not Auto Video does go black during loading of mission just wait thru it

 

 

 

 

 

If Above images are unreadable I've attached the photos in the zip file below. Please submit this bug to the Devs as these issues are Real out on our end. Also doesn't matter the setting in game lowering the textures and such still results in the same issues as well as whether 1 GPU is enabled or 2. Please also let me point something out 1.5 is supposed to provide better performance then 12.16.x, and I may have had less FPS around 40. But it was a stable 40 FPS with very Little dips in FPS with the TGP and Mav On. In 1.5 I'm seeing better FPS, but serious dips in FPS across the WHOLE GAME! I understand this is a Beta, but WE as a Community are not lying here. We love this game and would like to see it be the best it can be, but please report these FPS issues they are quiet real and is some cases Game Killing for us.

Of course it's set correctly, besides, if it killed the fps, it'd kill the fps somewhat the whole time. Not just kill it when FLIR is flicked on.

No. There is a report of wrong aspect ratio setting kills FPS when TGP is ON in a China community.

 

http://www.insky.cn/bbs/thread-65024-1-1.html

 

In this case screen is 1440x900 and aspect ratio is 4:3.

Although it may not be the cause of your problems, I 'd suggest that if you are using the Nvidia Adaptive vsync, in-game vsync setting should be turned off. That is something that should normally applied to all games - do not use both the drivers and the in-game same setting at once - it can cause performance drops.

Okie-dokie. Is that TGP in general or TGP with FLIR on?

 

Anyhow, I double checked my aspect ratio tonight, yeah definitely set correctly. Although everytime I go back into the settings I see 1.777777 instead of 16:9 :S, anyhow, seems like it's set correctly when I choose 16:9 and click ok.

Thats what I thought at first as well, but after an hour of trying many many different settings, the cause of this still alludes me, I still cant reproduce this, my FLIR view has no drops at all.

[Manuel_108]

FLIR BHOT or WHOT makes the game stutter extremely. Fps drop of ~25, completely unplayable.

[fjacobsen]

Strange ....

 

With my GTX560 1Gb (below min recomended) I have normally around 70-80 fps with medium-high settings, little stutter.

Turning on the TGp causes a fps drop to around 50-60 fps regardless wether I use CCD, Whot or Bhot.

I'm using a 2x AMD R9 270x 2gig these cards don't use nvidia, I tried vsync on other tests and still same result. I'm stumped. Also tested with modelview off, normal, enlarged same issue. My theory is there's a rendering issue for the map size within the TGP and Mav that causing the drop in FPS in cards with less the 4gigs. I'm starting to feel that it's about time for the R9 390x 8gig. But that only helps me not the guys also experiencing this.

I am using a 780GTX with 3 gigs, its rock solid for me, even with the cockpit res maxed, and AA and such maxed as well...

Our cards are similar, I see the frustration. What if it's a AMD thing?

People in this thread with Nvidia as well it seems, better cards than mine.

Can you test you're GPU usage, I've noticed that mine is at 100% on both cards. Even if crossfire disabled.

 

Ex:

Enabled

GPU 1 100% 1120 GHz 1024mb

GPU 1 100% 1120 GHz

 

Disabled

GPU 1 100% 1120 GHz 1024 mb

GPU 1 100% 300 GHz

 

Shouldn't the GPU be about 60% to 80%. The above are examples, but I'm in the 89% to 98%
