DCS crash that kills MSAA setting

[Pride37]

Hi,

2.7 with Reverb G2 here.

When I updated to 2.7, I noticed a slight performance impact in VR (nothing comparable to the 30% drop some are experiencing, though...) and BigNewy's advice to rename the saved games folder and repair seemed to make the job for me. Certain situations are still a bit more stressful for my rig than with 2.5.6, like populated areas or overcast with heavy rain, but still ok'ish.

So I started to enjoy cloud surfing. And then... DCS crashed to desktop (as it sometimes happens), but when I fired it up again, I immediatelly noticed the shimmering image as if MSAA was off in settings (despite it was on 2x, as usual). And then, whatever the setting I put (Off, 2x or 4x), nothing changes and the game doesn't restart as it normally does when validating the settings (which is a good clue that something is broken).

I do the "rename saved games folder/repair" thing, and MSAA joy is back... But every 4 or 5 missions, the game eventually crash to desktop again, and I have to do trick all over again, which is quite a PITA, to say the least...

What is weird, is that when MSAA is broken, I don't feel any performance gain as if it was normally off...

So for the coming days, I'm back to pancake with good old trackIR to enjoy the beauty of 2.7 (no experience with 2D 2.5.6 to say if I gained or lost any perf...)

 

Any clue for what could break MSAA ingame??

Hi, 

 

I have not noticed this myself. We do have an issue with MSAA if it is applied and DCS is not restarted. 

In a future version changing MSAA will force a DCS reboot. 

 

Can you attach your dcs log the next time it happens so we can look for clues. 

 

thanks

Hi BigNewy,

Thanks for your quick reply. Next time it happens I'll attach the log.

I fully understand it's Open Beta and things still need to be tweaked, it's normal considering the huge job you've done for this awesome update, and I'm confident that major bugs and perf downgrade some of us are experiencing will be sorted out soon.

Keep up the great job!

I wonder if this has something to do with the MSAA mask.  You can adjust that mask down so that you have no MSAA applied, but it doesn't come with a performance improvement.  I wonder if that is related to the way that you don't see any MSAA but still see the performance drop as if it was working.

MSAA mask was in 2.5.6 it doesnt work as a performance tool. because of when the effect is added in...

Hi BigNewy,

Happened again 15mins ago.

I installed today's new patch, renamed again saved games and did a full repair. After that, it was really working beautifully, both in 2D (all settings maxed out) and VR (pretty high settings also.) Free Flight mission in Syria with Hornet, this map used to stress my rig quite a bit in 2.5.6 and I have the feeling I have a bit better perf than before.

Exited the mission and tried to lauch M2000C night landing in PG, and BAM... Crashed to desktop (in 2D this time, not VR but the effect is the same.)

I restarted the game, and immediatelly found MSAA was broken again and was unable to put it back on.

Attached herewith is the log (not sure which file you need, so I put all 3...)

I have the feeling that if I want to avoid CTD, I need to restart the game between each mission.

Thanks in advance for your help.

Edit: Oh, and I forgot to say that I also lost about 20 to 30% in perf on the same mission after I restarted. I know it sounds like what many other users are currently experiencing, but I know it will be back on good perfs with the "rename saved games" trick... At least for me...
