Re: Car runs rough on idle

Why would you not do that as soon as cars had ECUs?!? Throttle response. I hear you, but the throttle response on a servo-driven throttle isn't perceptibly worse than cable driven - with the bonus that proper fueling is FAR better since the ECU can set the proper pulse widths and ignition timing as...

Re: Battletech game coming out

There are mods to fix most of the annoying things, thankfully. I bit the bullet and started a modded campaign yesterday and it's a lot better with a couple simple mods for line of sight, targeting percentages (just to show what the actual calculation is), sprint melee, and camera controls.

Re: Battletech game coming out

Yeah - it's scratching that Battletech itch (and I love it! I'm in 63 hours of gameplay so far...) but some of the rules / interface decisions are just odd. I honestly don't dislike any of the mechanics, it's just how some of them are kinda hand-wavy and lie to you that bothers me (especially headsh...

Re: Battletech game coming out

I'm not opposed to them being rare - but if the percentage isn't 18%, don't show me 18%. Missiles, from what I understand it, are individually tracked, but only one missile per launcher can ever hit the head - so you have more chances based on both number of missiles *and* number of launchers. 4 LRM...

Re: Battletech game coming out

Same. You're better off just focusing down the center torso. Headshots are basically impossible, even when it says "18%". I think that's what bugs me. 18% should be 18% should be 18%. Not some magic math that I can't see. :/ I've started just coring out mechs from behind if I don't have e...

Re: Battletech game coming out

I seem to be perpetually unable to make headshots on the enemy. I hit from higher elevation, bonus accuracy weapons, called shot master/bonus, etc. It just doesn't happen. I even save-scummed when trying to get an Orion in one shot and I gave up after about 15 save reloads. WTF am I doing wrong?

You're going to roflstomp the main campaign. Enjoy it!

I'm on my second playthrough, trying to stay more to character this time (my wife created the background for my new commander). Lots of punching and melee focused builds, reckless abandon for safety, and a damn fun time.

Maybe I'm a bit out of date - I was under the impression the SK-X chips took significantly more voltage to get near 5 GHz even with a handful of cores over KL/CL.

In any case, I would certainly hope that any system on the scale of that new ORNL deployment would be using ECC RAM... Absolutely.

HBM2 sounds interesting but in its current incarnations it's great for GPUs (high bandwidth) but not so great for CPUs (too much latency even if there is a lot of bandwidth). HBM/HBM2 are pretty comparable for latency...and they are both measurably faster than DRAM due to various factors (proximity...

Re: One memory channel per die THANK YOU AMD!

It's not one memory channel per-die, it's two-per-die with the other four disabled. This creates issues with higher latency for memory access, although to try to alleviate that the platform officially supports DDR4 3200.
