Random FPS drops after getting new monitor

So for the last few years, I’ve used a 10-15 year old HD TV as my monitor, where I had really high FPS (even if I couldn’t use it) on insanely high settings, only Naval has been an issue when battleships are involved (and even then only some of the later refit ones at like 6.7 or higher) that made me lower my FPS and see some improvement going from ‘movie’ to ‘maximum’. But the other day I got a QHD Odyssey G5 on sale since the TV was starting to have issues even turning on. And while the picture is great - I’m having sudden issues with the frame dropping from an average around 130, to 60 or less. And the thing is - in Naval, there was at least a certain consistency where I could go ‘maybe it’s graphics changes they’ve made even though other stuff says I should be fine on insane settings’ when you had a bunch of large ships firing literally hundreds of small caliber guns at the same time. But the last couple days trying to knock out tasks in air for BP points and all - it’s been horribly inconsistent when it happens, and while it was bad in Naval, it’s worse when your in a 12 plane furball at 200m or less.

But here’s the rub - if it was always happening in the 12 plane furball, I could once again go with ‘maybe I need to lower my settings’. But sometimes - I’m in the middle of a 12 plane furball at 200m with planes exploding in to pieces or catching fire all around me, and it’s fine. But when I respawn with only one other guy doing barrel rolls near me - all of a sudden it starts to stutter and drop to 80, 60, even a couple times 40-50. And then the next time it might be the reverse one guy is fine but surrounded it’s an issue. I haven’t been able to find a consistent thread that makes sense to either turn the graphics down, or adjust one particular thing. I even tried running it on ‘recommended’ settings which still goes to stuff even ‘Movie’ has turned off and was getting pretty high frame rates, and while the gap in the drop was lower, it was still just as random.

I tried turning the sync function off (it’s free-sync that’s supposed to be G-sync compatible but saw some things saying that could still be an issue) - but unless there is a step I missed beyond ‘turn it off on the monitor’ that hasn’t worked. I tried clearing the game cache, that seems to have had at best minimum impact. Made sure all my drivers and everything were up to date. But it’s only since I got this monitor it’s been like this - or because the frame rate it showed in game was a little higher on the TV averaging closer to 160-170 but capped at a lower refresh maybe it just wasn’t noticeable.

As to Hardware - I have a somewhat older PC at this point with an RTX 2060 with a 180Hz refresh rate (same as the monitor I now have for a change), 16GB of RAM, and an AMD Ryzen 7 3700X 8 core processor.

This is just a guess, but you went from 1080p to 1440p and from 60hrz to 165hrz . Your graphics card has 6GB of Vram so it might be that it tries to store to many large files in the Video RAM so after playing for a while it can no longer store the files on the graphics card and has to use the hard drive as temporary VRAM.

Also, this:

A graphics card doesn’t have a refresh rate.

I guess my first question is ‘how are we defining a while’. Because it’s basically from the time I boot the game up. Unless it’s something that’s built up over the years and have to clear somehow that I have no clue how to. Or some other way to fix it that isn’t ‘get a new graphics card’ cause I don’t have the money to.

I’m just typing what it says under GPU in the OMEN gaming hub. Unless that’s the monitors refresh rate cause I know it’s a 180.

I was refering to this part:

To me that sounded like the issue starts later in the match. Either way, if the issue isn’t consistent then it’s harder to narrow down as well.

Then that is the monitors refresh rate :)

In general a 1440p resolution has ~75% more pixels to deal with so that’s basically 75% more data your graphics card needs to send per frame and if you are using the higher resolution textures it’s also more data that needs to be stored in the Vram. Try lowering the resolution of the game to 1080p and see if that removes the issue (just as a test). You could also try one of the downscaling options so that your pc only renders in 1080p but then upscales to 1440p, it uses less resources from the graphic scard but might make the game look slightly worse sadly.

If you’re still having issues then you can bug report it here (just search a bit first so that you don’t report something that is already reported and known about): (Gaijin.net // Issues)

A guide on how to report bugs can be found here: ([Navigation] Technical Knowledge Base | War Thunder Wiki) , for performance based issues you will also need to provide som extra files, for example a performance log as described here: ( [Technical] Performance Profiler | War Thunder Wiki )

Yeah, that’s the part that’s been killing me as someone that’s done game testing and all. I decided to run a match with stuff to check performance - and it’s the one match I actually had no issue, and the game has been running when I’ve been typing these. Frame fluxed which has always been normal but no crazy stutter causing drops. Found out how to look at the VRAM - of the 6 that’s dedicated it capped out in the hanger of all places around 5.7, in the match (and since) it’s been at 5.0-5.2, with only 0.2 of the 8GB of shared memory being used.

That being said - it’s a map I hadn’t rotated in to yet during my play since I got the monitor, so I guess my next step to try and find a factor is track what matches have it, and what map/mode it is to see if that yields some kind of common denominator like maybe it’s the maps that have larger bodies of/are mostly water, ones with more ground targets that move and shoot back at you, or something.

I mean - I’ve played at 1080 (or worse) for since the game started until the other day, so if I have to go back to that it’s a tad annoying, but not the worst thing.

Unless I can zero it in to something more specific, like certain maps and/or modes, that likely won’t happen cause just in the last day there’s a half dozen or so FPS issue reports, so on that ground I’m not the only one having FPS issues in general at least.
