Once again game eating 100% CPU - Linux

twiistedkaos · 08-23-2007, 07:03 AM

System Specs
3.0Ghz Dual Core
2GB Ram
Nvidia drivers

before when I had this issue it was with the sound lib which caused the 100% cpu eatages. I noticed in the last few releases even without the sound and music, the game is eating 100% cpu. This may just be due to updates, and changes that result in more CPU power I suppose. But in the beta, I only ever used 40%-60% cpu.

Sorry noticed posting in wrong section, please move to Linux

I think its prolly just reporting it wrong, it's always said the same to me hovering at 99% in the in game info, but without seeing any preformance gains or hits when the CPU is either underclocked or overclocked, your best off just running windowed for a while and check usage with the system monitor or top.

Same here. Top showing 99%-100% all the time.

Yeah and it's green because for the game, it's a good thing

. If you have a dual core, it will use only one of the cores.

you don't want a game to take 40% cpu, you want a game to take 99-100% cpu

you can use nice (or renice) to change its priority down so it'll only take 40% cpu, but you're not gonna like playing it like that.

yes, those 100% usage are a Good Thing (tm)

Exactly,

The games uses all the CPU it can chew its teeth on in order to process more frames per second. You can minimize the game to diminish the cpu used but I don't recall if the game supports that right now.

Not if you keep the game running on a dual monitor setup

I think the question being asked is why does Regnum use 90-100% CPU when WoW running under Cedega/WINE uses about 45% of my CPU.

I see 75-90% on our dual Opteron 275 box. and no it's not my personal PC it's our SQL server.

A game (any game) will always take whatever is available, if a game is only taking 40% of the cpu, then something else is taking 60%, or you are interpreting the data incorrectly

yes, while the game does take very high priority there is a point where more power just doesn't help it, like if you where to take an older game from more then 5 years ago and put it on a decent machine these days you'll likely cap out what the game can actually use quite easily, I've seen a few ppl online ask why their old game only gets x amount of FPS when they have a new omega quad core boxx with liquid cooled overclocked everything. Is it the game engine not being able to make use of that speed or is it caped off in some way to have a max possible FPS and once it reaches that point it no longer tries to go for more, which is arguably the best way to do it. cap the game at 100FPS, no screen can do that and even the fastest of human eyes(think like fighter pilots traind for this) will have trouble ever seeing a skip. The question is then, why make the machine run that much harder for no precevible gain other then more player's going on about their e-p3n0rz because they get 2 more fps then the other guy or cause they got 5 more marks on 3d mark.

Why all of this? Simple, we precive unstuttering motion at about 16fps, so thats a bare minimum, tho we see it even better at 24fps, which is what movies in the cinima are played at, tho 29-30 looks smoother on the TV and it should be the minimm for fast action like a shooter, double that to 60fps and you're doing great graphically, 85fps is optimal tho, as most screens start to top out here in thier ability to draw frames a seccond, so a 100fps cap off would be fine for a max cap as if there is a small slowdown it shouldn't drop below 85fps for long at all.

So what am I getting at? Well anything over that 100fps would be wasted cpu and gpu power which draws more electricity and produces just that much more heat. Now I am an overclocker with my own systems, but I only like doing it if I'm actually going to need the power for the tasks I'm going to do, like for video editing, playing around with blender 3d and other power hungry tasks, but I also underclock my cpu if I don't intend to be doing much, as before I started playing regnum I actually had my system underclocked to where any lower and it wouldn't start at all lol, as who needs 3Ghz of power to download torrents and browse the web? Taking the cpu to about 950Mhz, down from 1.8Ghz stock, or 2.8Ghz overclocked lowers the power draw a bit, as does dropping down the GPU speeds to below stock, on the low end the sem actually can run fanless with the monster sized scythe ninja cooler I have lol.

But then I'm a little nutz when it comes to my equipment.
