The problem is as shown below - flickering geometry all over the place. The sim is okay until I happen to look upwards or to the right in cab-view, and then this happens, and worsens until it becomes unplayable. I have no problems with any other stock on the Portsmouth route (just this latest add-on). I checked my temperature settings and, under full load of Railworks on this route, the GPU varies between 65-72 degrees, and CPUs around 48 degrees (which is typical for my PC under load). The PC is an i7 3820 clocked at 4.1MHz, with 16Gb DDR RAM and a 3Gb nVidia 580 card. Drivers are very recent (though might not be the very newest). I run my game on higher (though not highest) settings.
Thanks in advance for any help. I'd love to get this sorted as I used to travel this route using this stock, except in those days I didn't have flying triangles zipping around my head!
