Very low FPS on GeForce GTX 560 Ti

[ITA - Jack]

Hello!

I'm experiencing very bad performance in MP. The strange thing is that all was well until yesterday. The only change I made was to buy an SSD some days ago (that should improve the performance, not decrease it!). The server I'm used to play in is currently using the "Domination! 2" map. Before this map, we were playing on another Altis map (co40 something). The number of players didn't change and the others seem not to be affected by this problem, so I'm really confused about it... maybe drivers issue?

These are my specs:
CPU: Intel i7-2600K (OC up to 4.4 Ghz) - the CPU's load is not very high (under 30%)
GPU: MSI nVidia GeForce 560 GTX Ti Twin Frozr II/OC (1 GB GDDR 5 @ 4200 Mhz)
RAM: 8 GB 7-9-7-24 DDR3 @ 1600 Mhz
Resolution: 1920px * 1080px
OS: Windows 8.1 Professional (64 bits version)

GPU's memory got saturated immediately once I enter the game (I monitored it via the MSI Afterburner utility). I tried to reduce texture's quality, disabled AA, shadows, blooming effects - everything! Just to remain with less than 10 FPS. In the SP missions I can get 30 FPS, but not more than that. I even tried to tweak the game's configuration file as described in other posts with _no_ results.

I'm currently using the GeForce 331.58 GPU's drivers (latest up to 21/10/2013). I don't know whatever to try, I don't really think my G-card is THAT outdated, it performs very well in other modern games!

It turned out it was NOD32: disabling it makes no changes, I had to uninstall it. AFAIK it's the BattleEye service which will interfere with the antivirus' HIPS service (at least reading on some forums about nod32 and BattleEye). I think you'd contact the BattleEye guys and let them fix this, very annoying I have to eliminate the antivirus (I paid for) for a game.

If I were you, I would totally ignore the ARMA3 multiplayer for now.
