I'm playing Half-Life 2, Episode 1 on a mediocre laptop. Half Life 2 ran perfectly after tinkering with the video settings. I understand that Episode 1 is more demanding on the graphics.
The problem: after a few minutes of playing, without any issues, the game slows down and movements become jittery.
In earlier Half Life 2 games it would either run, or it wouldn't – making tinkering easier.
As of now, it seems that something during game playing goes awry and slows the game suddenly down. It doesn't happen gradually; somehow, at a given moment, it just jitters and abruptly slows down to an unacceptable level. It happens indoors, outdoors, enemies coming in or not, i.e., randomly in terms of game location. It seems to happen often after 5 minutes of game play or so. But sometimes it keeps on running smoothly longer.
I did tinker around somewhat with the texture detail and water reflections because I'm aware they are over the recommended settings. I also shortly tried disabling HDR and enabling bloom (whatever that may do), but troubleshooting is difficult due to the delay of the problem onset and sometimes randomness of slowing.
Any ideas what to do? Especially my knowledge on anti-aliasing and filtering is very poor and the game doesn't recommend settings for these options. I copied the settings from half-life 2 to Episode 1. Somehow the Radeon software suggested settings for HL2 that worked like a dream, but I can't get the Radeon software to work anymore. So I copied the settings from HL2 to Episode 1, in lieu of something more constructive.

I thought to provide the solution to my question here. Apologies for the noobieness, but for me it was quite a steep learning curve :
1) Cap the frame rate to 60 Hz (equal to the refresh rate of my monitor). In half life this can be done with fps_max [fps] in the console. I now use RivaTuner that comes tagged along with the freeware MSI afterburner to globally limit the framerate. Capping frames to the monitor's refresh rate doesn't impact gameplay. The gain in temperature is in the order of 10oC, likely due to the dynamic framerate of HL2 that peaks at rates exceeding 100 fps at times.
2) Disable HDR - I use a BenQ gaming monitor that also corrects for dark areas, and I see not much of a difference when turning high dynamic range off in HL2. Saves perhaps a few oC.
3) Lower water detail to simple reflections; I don't notice too much of a difference really and it saves quite a few oC when in watery environments.
4) Lower shadow detail to medium: may or may not help, but I do it anyway as it goes pretty much unnoticed, at least to me.
5) I replaced my mediocre laptop cooler with a Cooler Master Notepal XL. It features a fan airflow of 89.8 CFM, which is pretty good (as opposed to ~20 CFM of my previous cooler), However, the benefits of laptop coolers, other than raising the laptop from the bench, are disputed and so it's on the bottom of my list. I didn't check out whether it truly makes a difference. If any, it won't be much more than a degree or two.
My prime contributor to gameplay is texture details and that's left intact at very high.
In all, no loss in gameplay and a stable 75-85 oC with no drops in framerate.
