So I have had this graphics issue for some years now. The strange thing is that it only crops up over the cummer months each year, when my room is considerably hotter than it would be otherwise. So I am guessing it is something overheating?
Up until now I figured it was probably my GPU, but I recently got a new one and the problem persists (with its temperatures being fine).
So, I have moved onto the CPU. I know it occurs whilst the CPU is at 75C+, maybe lower, I am not sure. Bare in mind that I do not know if the CPU is the cause at all.
The problem itself
Whilst running in a straight line for example, the graphics just sort of stop and start, although my framerate does not drop during this time, which is what is really odd.
If you look at the following video, and closely watch the flow of the water, you can see it happening. It is particularly obvious in the last 5 or so seconds of the video.
You can also sort of see it in this video that I took today (ignore the regular stuttering). Once again, it is most obvious towards the end of the video (from about the 7 second mark).
So, any ideas guys?
