First CTD..

[GPatricks]

The game has been virtually unplayable due to FR stutter/pauses but yesterday it paused and then crashed, so maybe there is something in the crashlog to point me somewhere?

Hi the crash seems to point to the gpu driver crashing.

 

It maybe worth a fresh gpu driver install to see if it helps

Thanks Bignewy. I just posted this (below) in the "Game Performance" forum as being "Possibly Solved", hopefully it solves the CTD issue also..

 

I've been having issues with FR pauses since trying out DCS 2.5 on this machine with the new G-Sync monitor. I get 144 FPS (running at 144Hz) and then it drops to 0 for 1 second, then back to 144 for about 5, then back to 144, and on and on. Disabled wireless stuff and deleted drivers, deleted the two shader folders (mentioned somewhere here), dropped my graphics sliders way down, tried pre-load at minimum and maximum, then just upgraded from 16GB to 32GB RAM. Same results in my tried and true P51 Instant Action Ground attack mission, which surely is not demanding with two planes and about 10 BTRs.. Today I set my G-Sync back down to 60FPS, hopped in and played for 10 minutes with not one pause. I'll try it a few more times but *maybe* the problem was pushing out too high of a refresh rate with G-Sync? I hesitate to say "all is well" but thats the 1st time I saw 0 stutters.. Yesterday it paused and stayed paused for the 1st time, CTD (reported) and prompted me to try this today.. Fingers crossed, because it seems that many of the problems are on new high end machines and most/all are G-Sync or Free-Sync capable..

 

Edit: Flew P51, Sabre, Mig 15 all with 0 pauses. Got ballsy and set all graphics to High, Pre-load to max. Flew the P51 again, 0 pauses, 60 FPS steady! Guess i'll start to dig in now that I can actually play!

good to hear you may have resolved this.

Not resolved, just took longer to start the 7 second and pause fun again. I'm done chasing this for now, I can fly BMS all day without issues, this is crazy...

 

Edit - being a glutton for punishment I ran another mission with MSI AB running, GPU hit 85C as a max, stayed about 83C for 10 minutes, saw no stutters/pauses this time.. I'm going to DDU the drivers and reinstall, see if that helps!

I fly DCS all day without issues,

 

Your crash seems to be a driver related,

 

A clean install of your GPU driver may help.

Just an update, and as the sim hasn't crashed i'm mostly on the "Game Performance" forum..

 

Did a DDU Uninstall in Safe mode, installed the newest Nvidea (431.60?) drivers, raised the laptop off the table to give fans better airflow, and hopped into P51 Instant Action. After about 5 minutes of smooth play, with a high GPU temp of 75C (better than last tests, so thats good), the pauses came back again, about every 7-8 seconds, fairly steadily..

[BIGNEWY]

Laptop thermal throttling?

Laptop thermal throttling?

 

We thought that when I was at 85C GPU (no idea where the threshold is but I read 90+ sustained is NG) but this time GPU was 75C and CPU about 80, and I watched the CPU speed/temp in play, never saw it dip..
