So yeah...after the latest update, while I did notice a significant improvement in my fps, the game is still unplayable for me due to a constant, every 3 seconds, stuttering.
I was not experiencing this before. Multiplayer had FPS issues but single player missions were running perfectly smooth even in higher settings.
It happens every time, in every server, in every showcase, even in a completely empty stratis map, even with 500 vision range and everything low/disabled, right off the start, non-stop, even right after turning on the PC!
Windows 7 64bit - Fully updated, scanned, registry clean
AMD Phenom II X6 1090T ~3.2Ghz
AMD Radeon HD 6800 Series: Tried with Catalyst Version 13.09 and 13.10 beta - no difference
8192mb RAM
Over 30% of HD space open, zero fragmentation
Using gamebooster, same as before this problem appeared, 0 fragmentation in arma3 folder.
.cfg:
No vsync
GPU_MaxFramesAhead=1; (tested with 1,000, 2, 3, 4)
GPU_DetectedFramesAhead=1; (tested with 0 too)
Played with video settings a whole day, even with everything to low/disabled it would still occur. FPS could be great, but the same stuttering would not go away, even in single player I repeat. High-Ultra settings, still very playable fps wise, stutter stutter stutter.
Steam&gamebooster launch parameters (same as before):
-noSplash -cpuCount=6 -high -exThreads=7 -maxMem=6144 -maxvram=1024 -noLogs -world=empty -skipintro
Temperatures are fine, no cores are parked, same as before.
I'm aware of all the AMD issues with Arma 3 but I repeat, I did not have this before! So unless it's a huge coincidence it's probably not hardware side.
I'm desperate!
