DreadMoth: Seeing this thread made me decide to try installing Heavy Gear 1 again.
Any ideas?
...
EDIT: Just to be clear, that movement problem happened with the 1.1 patch installed as well.
I decided to try installing Heavy Gear 1 as well, on Lenovo T400 Win7 64bit (Intel Core2 Duo P8600@2,40GHz, ATI Mobility Radeon HD 3400 Series). So not brand new hardware, but hey made in this century anyway! :)
At first I started playing with software rendering, and I apparently noticed the same problem as you, ie. the view bobbing is insanely fast, making it look quite comical. Also it had the same old colour problem as many other old Windows games in Win7.
But as soon I changed to Direct3D renderer, no problem, the movement seemed quite fine but then I don't know what exactly is the correct view bobbing speed in this game. In Direct3D the graphics looked fine otherwise as well, but I can't be fully sure how it is supposed to look, it's been a long time since I saw the game running before. I could try the 3Dfx option too, I have some Glide emulator installed already...
I didn't use any compatibility modes, didn't run as admin, didn't set CPU affinity or cores to any special values (frankly I don't even know how to do that) etc. So from my point of view, seemed to run surprisingly well.
Oh and I didn't even install either 1.1 or 1.2 patches yet either. I did download them from www.patches-scrolls.de and they came with absolutely no descriptions or readme files, so I have no idea what they are supposed to fix, whether I am supposed to install first 1.1 and then 1.2 (why else they are offering both patches?) etc.
With Heavy Gear 2 I've had a bit less luck. Seems to install fine, but running it on this same Win7/64bit PC causes the game to crash upon launch, no matter what compatibility settings or not I use.
With my older desktop PC which has ATI Radeon X800, HG2 seems to run quite fine though, even the graphics are fine without the earlier reported graphics culling problems on modern hardware. I tried to make HG2 work on this T400 as well just to see if I can reproduce the graphics problem on it:
