FPS decreasing with mission time

[SoulFlight]

Hello everyone,

 

so technical issues got me in this forum as well. ;)

 

I have been using DCS and FC3 for quite a while now and never had any fps issues I couldnt solve with different settings (with the exception of the BM-21 being a performance WMD).

 

But now, I got a strange issue: in the 3rd SU-25 campaign mission, a precision strike against bridges, around 10 minutes into the mission the FPS is continually decreasing from ~20-30, which is ok, to an unplayable slideshow level around 1FPS or even less. Pausing or SloMo gives me back normal FPS, but the mission is not playable that way.

 

Its a bit odd because judged by the F10 view the mission does not have more units than others I run without problems.

 

My specs are:

 

Phenom II X4 365 BE @ 4 Ghz

8 GB RAM

nvidia GTX560Ti

win7 64bit

 

Update: after clicking around here in the forums a bit I want to add that none of my components are overheating and this is not an occassional drop in FPS that vanishes after a while. I definitely have to quit flying to get out of the 0,5 FPS lag.

 

thx for any ideas ;)

How much Video Ram is on that 560Ti? Background programs like iTunes updating in the background could cause this, (Happened to me once) They give U no warning just start downloading Windows updates are notorious for this too.

 

Other than that I would look into the Cache/Swap File settings, what are they (Windows Controlled)? I would restart My PC before starting DCS a few updates back I found better FRAPs by doing this, a possible solution in ur case here.

 

The Drivers for that Nvidia are up to date I assume?

Solved: I updated video drivers but also found my Drive C: disk space is pretty low. I have a user-sized batch file on there reaching from 4 GB to 10 GB, but only had 1,5.

 

Now the problem seems to be gone. ;)
