I have the exact problem. The strange thing is that I can log into other servers without a problem?

Same here, confirmed

Verified tires will dissapear within an hour if moved . . .

Same here and on all servers!

I get the same, sudden slow frame rates and crappy graphics . . .

Her's the latest:

Uninstalled and deleted all Dayz folders, reinstalled and was able to play for 45 minutes. I didn't change anything in the cfg files. The last previous install I changed the following:

GPUMaxFramesAhead to 1
GPUDetectedFramesAhead to 1
sceneComplexity to 150000
viewDistance to 1600
PreferredObjectDistance to 1000

Was kicked to the desktop with the following error:

The instruction at )x))4a15d2 reference memory at 0x0edb0000. The memory could not be read.

Click OK to terminate the program

The zip file has the DXDiag inside along with the DayZ folder contents . . .

I uninstalled Dayz, updates raphics drivers, reinstalled (after deleting all Dayz files and folders).
Now I am getting the following error:

Cannot open file
C:\Users\JK???\Appdata\Local\DayZ\tmp\_cur_mp.ebo

Checking local files and everything is there . . .

Still getting a crash to desktop approximately an hour of playing time then game crashes. Doesn't matter if i'm in vehicle or nor. I started to think it was the 3rd person view when I was crashing but after playing in 1st person I still crashed to desktop. There is no error window giving me an error
