Guys! For those who have already tried V-Sync ON and FPS max 60 and it did not helped I tried something what was mentioned here... I added GameTime.MaxVariableFps 30 into user.cfg and now I am able to play China Rising maps without crash, Op Locker for approx 5 minutes (both 64 player and full servers).
I would like to say that game was crashing even in training range and campaing so now it is "rock solid" compared to what was released in patch on 13th february - however I am forced to play with significantly lower FPS. I am not saying it will work for everyone but you should give it a try at least. I know, it is just 30 FPS, but as EA and DICE does not care its better than nothing.
My user.cfg is here:
WorldRender.SpotLightShadowmapEnable 0
WorldRender.SpotLightShadowmapResolution 1
RenderDevice.TripleBufferingEnable 0
RenderDevice.ForceRenderAheadLimit 0
WorldRender.DxDeferredCsPathEnable 0
PostProcess.DynamicAOEnable 0
WorldRender.TransparencyShadowmapsEnable 0
WorldRender.MotionBlurEnable 0
GameTime.MaxVariableFps 30
WorldRender.FxaaEnable 0
PerfOverlay.DrawFps 1
Render.Drawfps 1
RenderDevice.Dx11Enable 0
RenderDevice.Dx11Dot1Enable 0
RenderDevice.Dx11Dot1RuntimeEnable 0
