FLIR - FPS killer

[Punisher74]

Guys,

 

Look at his "GPU2" is at 300mhz, "MEM2" it is at 150mhz.

 

As well as he is running 12x anti-aliasing and super-sampling. On cards that have 2gb of vram.

 

 

Sith's GTX780Ti that has 3gb of vram is running 2915mb in his screen( I do not know his resolution or Raptors) but, I doubt Sith is running 12x AA.

 

Hope you guys get it worked out.

 

Cheers,

Monnie

 

I ran tests at both gpu's at 1120ghz as well as 1 at 1120ghz and one off at 300Ghz. And that 12x aa edge-detect isn't the issue because at standard 4x there is still a massive drop in FPS. Also others are having the same issues as I am. And my resolution is 1920x1080p

Solved!

 

After setting cockpit resolution to 256 or 512, you must exit from DCS and start again! Restart DCS with changes is reason.

 

FPS on me with both MFD with FLIR is more than 60.

 

I don't think I understand the solution, I restarted DCS a million times. It's always the same.

 

I don't load it up each time to mess with settings anyway, my MFDs are on 512 now as they have been for two weeks.

 

Did this work for anyone?

No it only made it more manageable. And for me manageable is not fixed. what about you?

Like I said, I'd try it, but I think this is what I've already done every time I've started DCS and not touched the settings.

 

Unless he means you've gotta load DCS, change the MFD res, quit, load DCS again, every single time.

Ok no here's what you does. Set cockpit settings to 512 (not every frame). Close DCS completely. Restart then try settings.

 

Now I've done it. In crossfire mode I 120 FPS, but I still get dips to around 70ish with just TGP boat switch aft. And just above 60 with both TGP and Mav. His plan is more of a work around then a fix. Also if you're not getting the FPS that manageable then adjust the other things like msaa and other AA settings then work on textures and such. Until it's manageable for now. None of my shadows, hear blur, are on. And with the performance of my cards I should have FPS that's stable with TGP and Mav on and shadows on with a low heat blur and I cannot.

In nutshell, change of cockpit displays resolution settings requires restart. If you change from 1024 to 512 (for example), and enter an aircraft before restarting, displays will stay at 1024.

Ahhh, oh well. Like I said earlier I haven't changed my cockpit res in a week. Everytime I load in the fps when using FLIR is still borked.

 

Looks like I'm in for a looong wait to fly an A-10 again :\ Hopefully I can go back to 1024 every frame MFD res one day.

I don't have SLI nor Crossfire but I'm just wondering:

 

Do you have 120 Hz display?

Why many of you guys force 120 fps, when probably most of you have 60 Hz display?

If you have 60 Hz display, do you see any improvement with 120 fps over 60 fps?

If you have 120 Hz display, how much is graphic better on 120 fps than on 60 fps?

 

If you limit your graphic card on 60 fps it would provide much stable frame rate than on 120 fps. Moreover, graphic cards would produce much less heat which worms up other components and degrade its performance. Consequently allowing whole system to operate more efficiently.

My display is a Samsung 55" HD Display, I'm not sure if it 120 or 240 HZ, but that's neither here nor there. The human eye cannot tell the difference past 60. The idea is to get as much FPS at the high settings so vsync can keep the game at a solid 60, 80, or 90. And yes I know that. But at high settings and vsync with 1 card. I'm still getting those dips In performance. With out shadows or heat. 2cards it's ok, but everything flickers Also the fonts look blurry. Also with everything running(TGP,Mav) 2 cards vsync and pan around I get dips. So it's a workaround not a fix.

 

My goals is to max my FPS at 60 anyway, thru my card. It only works in crossfire mode. As I stated there are still issues with that too.

 

And others are still having issues as sith said a few pages ago.

 

I'm moving on to testing other things, like forcing crashes, freezes, multiplayer, testing in busy missions, etc.

You can check your refresh rate right click on desktop->Screen resolution->Advanced Settings->Monitor

In film era, measure was about 25 fps, so 60 should be more than enough.

 

I suppose that even you have more than average fps then monitor refresh rate there could happen out of sync situations.

 

I read somewhere on this forum that this beta release works better with VSync On in game settings especially for you with two graphic cards.

 

If your monitor have 120 hz or more, but currently(due any reason) your graphic cards can not handle that much, maybe lowering monitor refresh rate to 60 Hz could help. Because DCS will target 60 fps which your cards can achieve and keep in sync easily.

 

Do you use more than one monitor? I know that old graphic engine can't handle full screen when more then one monitor is set. I'm not sure for 1.5, I haven't try that yet but on one monitor full screen (when activated with Left Alt - Enter) works very well for me - no problems with out of sync situations. I have 60 fps steady.

Maybe you could try to use only one monitor(if you are trying to use more) and try to use only one graphic card if you can. Maybe you will get better results in a full screen. Your problems looks like you can't really get into full screen mode.

For the reference I have Gigabyte GTX 760. One monitor 1920x1200, Flat shadows, Shadows MED, DOF off, cockpit res 1024 every frame, all other setting max except visibility ranges which I left as default.

 

I agree. DCS 1.5 is beta released under pressure of community, so I'm sure that there are many things left to fix and improve.

just one 55", when I turn on full screen mode IE. LALT ENTER the font distorts (but kinda readable) and the clouds flicker.

Wau 55'' is huge. What resolution do you use? Is it native? Is that a TV?

 

I went back a little in this thread and see that you are using AMD. Unfortunately I've seen many times that DCS does not work very well with AMD. Hope ED will fix that soon.

 

EDIT: I saw your video now. I must admit didn't try A-10C. I've flying Mig-21 recently to learn something new... but I'll check A-10 and maverick tonight and let you know.

I upgraded all my Home TV's from HD to SUHD and I had 1 55" Samsung 240Hz HD doing nothing, so I decided to use it until I set up a Pit design in auto cad and had cut into its parts. but

Yea that's not so high resolution.

 

Anyhow, I've tried A-10C. Indeed I'm not getting so high fps like in MiG-21. I'm getting about 30-45 fps, although it looks smooth. There are also some drops when maverick is in use, but it does not cause any stuttering.

Also, I've noticed that buildings are flickering on TGP. I was flying 'Surrounded' mission, but I'm sure that someone has reported that already... and after 1 hour of flying crash.

All right, I'm waiting for next hot-fix hopefully this Friday :)

 

Btw I'm a little jealous when I hear that someone is building cockpit. I would really like that too but I just don't have enough space. But one day...

 

Now I see in your specs that your graphic cards have only 2GBs. That could be the source of your problems as I sow reports that DCS can eat more than 2GB vram. Maybe you lose performance on memory swapping.

Also, seems that some versions of AMD drivers have a memory leak in them, confirmed by AMD... but I believe that you already updated them to the recent version.

Good luck.

Sith has 3 gigs and everything is smooth, having 2 cards does help.

Maybe this is it.

Take a look on this post: http://forums.eagle.ru/showpost.php?p=2501339&postcount=37

 

DayGlow claims that he measured consumption of 2100 MB vram. This could explain why Sith with 3GB has smooth graphic and you with 2 GB have problems.

Try to measure vram consumption on your system, if you found 100% of vram in use, try to lower texture quality/resolution.

[NineLine]

Ok, so anyone here having this issue AND has a video card with 3 or more GB of vram?

[ody81]

Well I'm on 2gig.

 

Hopefully this is the root of the problem.

[NineLine]

If we can pinpoint that as the issue I can submit that and see if its something that can be tuned, right now, and correct me if I am wrong, but FPS tank even on the lowest settings for cockpit displays... anyways, let me hear, if no on with a 3GB or higher card is having this issue, I have something to report.

On the ground in a tank I'm fine 60fps on vsync. With xfire running 50% (see example below)

 

A-10c still 56 FPS VSYNC ON xfire 50%

 

A-10c still xfire disabled 46 FPS 1 card only turn on TGP and Mav 15fps.

 

A-10c still xfire enabled 100% 60 FPS vsync w/TGP AND MAV ON no shadows Period

 

In game ATF 16x, msaa 4x no shadows or heat. Trees 1500, preload 150,000, Enlarged, civ off, pit 512.

 

CCC settings:

Everything to use app settings

Anti-aliasing Edge-detect 12x

AA filter multi sampling

 

Xfire definitions

50% 1 card 1120ghz, MEM 1400mhz

1 card 300ghz, MEM 150mhz

 

100% 1 card 1120ghz, MEM 1400mhz

1 card 1120ghz, MEM 1400mhz

 

Disabled 1 card 1120ghz, MEM 1400mhz

 

Cards: 2x MSI R9 270x 1120ghz 2gigs DDR5 MEM 1400mhz

 

The issue is the rendering on the TGP and MAV light filters and objects. In DCS 1.12.6x the rending in your pit at 1024 didn't seem to affect the TGP and MAV. In order to have 512 as a pit the text in a-10c blurs out. Set the TGP and MAV to always render at 512 so the pilot can set his pit res to whatever 256, 512, 1024. Also combined with the high memory consumption the dips in FPS without vsync are huge. My previous posts without vsync still stand with the dips in FPS vsync and settings in this post make the game playable with xfire at 50% & 100%. Not so much with 1 card even with medium settings in DCS.

I have the problem on a 2GB card as well.

[Runibl]

Have not noticed any fps loss myself, but wanted to check it out anyway since more information doesn't hurt.

 

I can confirm that the loss of fps is there, but not noticeable since fps is nicely high for me anyway, but it is there. The loss is about 30-40 fps.

 

Did a short video while testing:

 

Specs in signature

Cockpit screen resolution: 1024 (Not every frame)

Monitor res: 1920x1080

Single Geforce GTX 980 4Gb vram.

 

Attached dcs settings screenshot.

 

Again for me, it has not been noticeable so far and has felt very smooth. But can clearly see, that this can be a problem for someone with lower specs.

 

Edit: This was with a completely fresh install of beta, no files transferred from previous install.

I'm sporting a 980ti and I have similar fps drops, albeit the fact that it seems to be the TGP in general.

Whenever I bring it up in an MFCD, I drop from say 110 to 70. switching to FLIR I drop another 10fps.

I have a 4Gb card, but get the same huge FPS loss when switching the TGP from CCD to either WHOT or BHOT mode.
