Flickerin TGP and MAV displays

[Galwran]

Hi.

When I use either the TGP or mavericks, the picture of the MFD flickers about once per second. Its pretty nauseating :(

 

I'm using GTX295 for graphics.

[Galwran]

Silly me: it seems that the solution is to select mfd resolution "512 every frame" or "1024 every frame" in the options. :pilotfly:

[Der.Brizon]

I only ever experienced this problem when it was set to 256. 512 worked just fine.

 

Except now that I upgraded my machine, the game simply fails to render anything properly, so I haven't bothered to test anything out.

Thats good to know. I have the same card and had the same problem. Thanks :thumbup:

SLI Causing Graphical Artifacting on FLIR and IR sensors

 

Just wanted to bump this to get some developer feedback that they are aware of the issue and to clarify the problem.

 

The problem:

IR maverick and TGP FLIR cameras are showing graphical corruption in the form of flickering, wireframe mesh showing through the ground texture when looking at the MFCDS.

The cause:

This is caused by running an nVidia SLI configuration

 

The (temporary) solution:

It can be fixed by setting "Res. Of Cockpit Displays" to an "Every Frame" option (eg. 1024 Every Frame). Disabling SLI also fixes it.

Expected result:

The performance impact of having to run at even "512 Every Frame" is too much compared to just "1024". SLI is making a large benefit to the sim's performance. I would like to be able to use SLI and the less taxing "1024" setting. At the moment having to use an Every Frame is negating any advantage of SLI.

Other notes:

The fact that it doesn't seem to occur with the CCD camera (I also never had this problem in Black Shark) gives me hope that Eagle will be able to fix it without having to wait for nVidia to make a profile.

 

Can any of the Developers let us know their stance on this kind of problem?

 

 

I understand you guys are very busy and imagine it can be annoying being bombarded by lots of questions relating to development and bug fixing when it comes to us external, 2nd tier of beta testers. But, we don't know what's going on behind the scenes so we may unwittingly be asking about something you know about, have plans for, or may even have already fixed. So please bare with our inquisitive enthusiasm :)

I'm sure they are aware of it. I had to disable Multi-GPU config from the control panel to stop the flickering. Even with the "every frame" resolution it kept showing flickering. I didn't have a big drop in fps though.

[OhmWrecker]

One thing to note is while disabling SLI is an option, that also means that if you're running three or more displays you get bumped down to two. I run three Alienware AW2310 120hz panels, and have A-10C set up for a 5760x1080 resolution. NVIDIA requires two cards to run three displays in surround resolutions.

 

Thanks for the tip on every frame, I'll have to give that a try.

[BTTW-DratsaB]

Still having big problems with this in Beta4.

[RSharpe]

I got serious flickering above a T-55 on my TGP as I was passing overhead while zoomed in. I noticed that when I zoomed out a bit that the flickering stopped, but when I zoomed back in, the flickering started up again. This was using Beta 4

[Frederf]

I'm getting what appears to be Z-buffer fighting at high zooms and close ranges on objects such as a T55 through the TGP. http://en.wikipedia.org/wiki/Z-fighting

 

I am guessing that this effect and flickering MFCDs (the entire display flickering) are two separate phenomenon.

Have you tried the "every frame" tip as a temporary solution? It works for me, although like others have suggested it also kills the gains you get with SLI active.

[Napa]

I'm still seeing flickering on TGP and MAV displays on beta 4 even though (AFAIK) I tried all possible combos from in GUI options and nvidia control panel. The only way to stop it is to disable Multi-GPU config from nvidia CP.

 

Hopefully it will get fixed in beta 6. I really want to use both GPUs.

 

I wonder how Matt Wagner managed to fix the flickering from TGP and MAV displays. I saw from his sig that he's using the same card although he could be producing those videos from another rig.

Yep, I noticed the same. Fingers crossed he has it on his list of things to fix. At least we know the Lead Dev has the exact same problem as us :D .

 

I notice Crossfire users are getting some attention in the coming Beta, hopefully SLI users will too.

 

I know it cost too much performance, but have you tried "512 Every Frame"?

[tonym]

Try 246 every frame. This cures flickering completely.

That actually works.. I have no idea how I missed that before. Although I don't like this "every frame" concept.. I wonder how much impact it has.

That doesn't work IIRC. Really strange. Only "512 every frame" works. And its really fps hungry, especially with Mavericks. IIRC the TGP is a little bit smoother.

 

I'm going to give all modes a try one more time when I finish work. I bet it has something to do with the new drivers. I remember very well a couple of months ago on beta 4 (before the new nvidia drivers) that it didn't work. I bet those new drivers must have something to do with it.

Quite a lot from tests I have done. Ignoring the flicker, I can run 1024 setting with no real performance issues, but swtich to 512 every frame and I loose a bunch of FPS when one or both optical sensors are active.

Yes, there is no 256 Every Frame option, not that I would want it tbh beacuse it looks ugly as sin, I can barely stand 512. 1024 looks so sweet.

It hasn't worked for me since I got DCS:A10 (beta 2), I don't think it is the driver either. But one way to find out for sure (I just thought of :) ). If you play Blackshark (I have it but haven't played [ahem "flown"] in ages) you could see if the non every frame option in that causes the same flickering. If it does then it is a driver change that caused it, but if its ok then it's DCS:A10 that needs fixing. Edited February 17, 2011 by BTTW-DratsaB

Still present in Release

 

Unfortunately it seems this bug is still in there now we have release. Does this mean we have to wait for nvidia to make a profile to fix it?

 

Did some testing of FPS and flicker, may as well post it here.

 

Used replay: "JTAC Demo Mission"

Waited for turn on of TGP and acquisition of first target (APC).

 

Res. Of CockpitDisplays FPS Flicker?

256, 41 FPS, Yes

512, 38 FPS, Yes

512 EveryFrame, 33 FPS, No

1024, 37 FPS, Yes

1024 EveryFrame, 30, No

 

As I said before, Wags has a 295 and flys with 256 setting. I guess he has SLI disabled?

 

Its a damn shame I cant run 1024 setting, hope this can be fixed soon.

[rockyalexander]

I have a single ATI 5770 and am also getting some bad flickering in the TGP display when zoomed in. I have the resolution set at 512. I just can't spare the FPS to run the rez at every frame.

[OhmWrecker]

I'd just like to bump this thread because it's still an issue and it's something I'd love to see get resolved. I can report that the issue exists even in Nvidia quad-SLI as I now have two GTX 590 cards but the performance takes a dive at 5760x1080 with every frame mode on.

[Darkstorm]

I have the same issue with my Quad SLI setup and with the very latest drivers that nVidia released at the beginning of June. I know my 9800GX2 cards are getting long in the tooth now, but even so. As soon as SLI is disabled the issue goes away.

[Darkstorm]

An additional issue has now also shown up in the Training missions

 

I have a Dell 3008WFP A02 which is capable of 2560*1600

 

If the display resolution is set to 1920*1200 then the simulation hangs the computer with a screen freeze and I have to carry out a forced shutdown and restart.

 

Drop the simulation resolution to 1920*1080 and although I now have part of the Desktop visible I can now see what tbe issue is. The simulation window screen flickers as soon as the OK to start the training is selected, goes all green and then reports that the video driver has crashed and been restarted after which all is well. Very odd, and it does it every time.

 

System specs are

A10C 1.1.0.7 - I'm leaving 1.1.0.8 alone for now.

XFX 790 FTW Digital mainboard

Intel QX9770 CPU @3.4GHz - no overclock

8GB DDR3 RAM

Dual EVGA 1GB 9800GX2 in Quad SLi

Windows 7 64-bit SP1 and patched to June 2011

On-board sound

All current mobo and GPU drivers currently avail from OEMs

[RSharpe]

I'm starting to think that this isn't a problem that ED is capable of fixing, which would be very disappointing.

[A10FAN]

I was getting the flickering in my right mfd tgp screen and then i set 1024 to every frame in the options screen and it went away

[snwboardn]

Yea I just got a 590 and the flickering went away at 512 every frame, but the gridline problem happens whenever I zoom in and out...
