Frequent post-patch crashes/reboots from game

[Russkly]

Right, after some more testing (delayed when a Firefox-inspired System Restore screwed up Steam so that I couldn't get into CoD!) it is clear that CoD is baking my GPU.

First off: GPU controlled by ASUS SmartDoctor software. HyperDrive on but set to Cooling mode, not to 3D Games mode. Fan on Auto. So, GPU will be driven to run cool rather than run performance.

I turned the res down to 1600x1200 and flew the 6 Hurris vs 6 109s over water quick mission without problems (at game settings posted earlier in this thread).

Hoorah!

Then got cocky and tried the Hurris vs Ju-87s over Manston quick mission at 1680x1050.

No problems over water, but as soon as I came over land to head home - bang!!!! PC reboots itself.

SmartDoctor doesn't have a log facility like MSI Afterburner, but, having used the latter, I am sure that the GPU was maxed out at that point and simply rebooted the PC to avoid heat damage.

I'm not sure what to do now - I'm loathe to turn the settings down further, because they're hardly maxed out, and my system's not that bad (is it?). And I don't really want to install some water-cooling system for 1 game - RoF never gives me this problem on pretty high settings for example, and nor does Arma 2.

Any thoughts? Will any of the upcoming patches address this; or is it something I'm doing wrong; or is my GPU simply too wimpy?

Shame, because @ 1900x1200 at the game settings above, it looks wonderful.
