Massive sudden drop of framerate
-
And another temperture profile
-
What’s the GPU temps at 18 mins?
-
can you please give 32 bit a shot, just to make sure it behaves the same.
-
Yes sir, which means I’ll get back to you folks in probably a little under 20 min
-
32 bit makes no difference…
Regarding the GPU temperture: at a steady 64 degC until the issue starts, then it rose to 70 degC, a clear sudden increase in temp is visible in the attachment
-
Right so what is the throttle back temp for that card? I remember an old GTX-670 I used to have throttled back at 69 degrees by default.
-
in falcon config,
make sure “Hi-res textures” is OFF
and you can try turning off some shaders, consult the BMS manual in the FPS optimization chapter as for which shaders to turn off first.GC throttling might be the case, or maybe it’s out of memory or something. so let’s try reduce its workload and see if that makes a difference.
-
I don’t know the throttle back temp for my card, and can’t find it right away, but Catalyst control center tells me the current 71 degC is no problem, fan running at 64% and it’s not throttling back either… Flying around in DCS now with these conditions, all steady so far… I actually doubt it’s the workload on the GPU because it performs fine in other applications such as DCS

Yeah you might want to find that out…because if it is throttling back then your game will be a stutter fest.
It was actually DCS World that used to run my card ragged however if you are running DCS World 1.5 that will likely be far better and wont get the same resource issues as previous versions.

2.53 GHz is probably a bit low for 4.33, you need CPU power, above 4GHz is good!.
-
Quad core wont run it? 20min suuupersmooth and then.it breaks… Seems odd to me to blame it on the.cpu clock…
-
I overclock my CPU to 4.4GHz from 3.(something, can’t remember), and it makes a huge difference for me, more than any tweaking of my GPU does.
-
I OC’d mine from 3.3 to 4.5 and it made a HUGE difference in BMS. OC to 4.8 and 5.0 and law of diminishing returns kicked in. I gained only a few fps after 4.5, and less at 5.0, so I backed it down to 4.5.

Same experience here for the first time. After flying 4.33 64bit for 2 weeks now, never had issues.
Today Steady 40-60 FPS during Kunsan-airborn as usual. Doing MP with 1 other human player, 16 runs of LGBs with buddy lading for testing. Frames dropped to 25 when TGP on (normal).
But after 1h45min of flying, suddenly I got 20-25 looking outside with TGP off and a creakingly slow 8-10max (unworkable) when heads down (tgp off).
Didn’t have any profiling software or so running. No idea what caused it. -
Focaldesign your issue inspired me to install 4.32.
I flew around for nearly one hour withouth any issues. Constant good performance throughout the entire session.
This reinforces my suspicion that it is a software issue with 4.33 itself

Hi, just had my first experience with extreme framedrop.
Normally I had >30fps in campaign and stutter free gameplay. But now after day one and ± 11:00 hours into campaign slowly my framerates started to drop, but also small hickups.
Ultimately the fps becomes <14 and totally unplayable. Even after 2 different missions and saves in between the issue stays.
Strange thing is after some investigation was that the drop is also noticable in 2d menu (campaignmap, mouse movement and in tactical reference while rotating)
First I thought something had changed on my side, but after restarting a new campaign my framerate where normal again >30 and everything smooth.
Reloading the first saved campaign brings back the framedrop and stuttering.
Then started a TE and framerates returned to normal.I am flying 64bit, but also tested using 32bit, but same result.
Also already played earlier campaigns in which I did not get the framedrop issue.This last campaign I did schedule the missions manually for the 80th only and also used the autoupdate option for weather files, but not sure if this could be related.
I will start a new campaign and see if and when the problem returns.
Another thing I forgot to mention is that when I pause the sim when the issue is there and <14 fps, the framerate increases to stable 46 fps?
Cheers Obi1

I too have strange things appening. In general I have quite many stutters even if the frame rate is ~60. Then, after a while it drops down to 40-50. So I have noted that if I ALT-TAB out of the sim and back, my FPS return to 60 and no stutters!

Same thing happened to me yesterday. Done about 80 flight hours in 4.33 and it’s the first time it happened. Take-off and ingress were fine (around 60FPS), then suddenly BAM … slideshow mode until I landed and exited.
2-ship MP flight with me hosting. My wingie didn’t notice anything on his end.

Theater: Balkans for 4.33
System specs in sig. -
I’ve recently performed a complete clean install of my system. It worked okay after that. Did some multiplayer mission with someone. Worked fine for a while, until it crashed. Now BMS won’t start (CTD on startup) .
I’m giving up. Might be hardware related after all… I’m going to save up for a few months and upgrade my system… :<

I experince the same problem since 4.33 installation. However, it seems it depends on capaign/theatre (how many units in the air and on the ground) and probably hard disc access. Disc not swapping (16GB RAM total, 9GB RAM free). Processor (Intel quad core 3.1 GHz) working on 70 - 80% power, but during stutters it peaks up to 100%. Stutter lasts from 1 - 3 seconds and FPS drop to unbearable 2 - 6 FPS.
