[104th_Cobra]

Hi.

DCS is crashing while entering a mission with this crash log text, only on the Viggen, on singleplayer and multiplayer. The same crash log text on 1.5.8 and 2.2.0.

Latest Nvidia driver. Tried to clean display driver and reinstall, no joy.

After testing stop the Asus GPU TweakII application (on a Strix 1070 OC), no crash has happened so far.

[104th_Cobra]

Yesterday, after read somewhere about problems with this specific *.dll I tested the Nvidia GeForce Experience in-game overlay (FPS counter) and CPU/RAM overclock (I7 975 at 4GHz, DDR3 1600MHz XMP profile).

 

It seems the last two Nvidia's drivers iterations are having problems with overclocked RAM. No crash after testing the Viggen cockpit and a long session with a Combined Arms SP mission.

Great news!

Yep, after not overclock the CPU, no crash happened, as I read somewhere about this problem with Nvidia last drivers, on other applications. After the memory leak on 2.5 Beta it's solved, I'll test again.
