good pc > bad performance

[manne]

I always noticed that BS didn't run that fluid on my pc, but today I finally checked my FPS. It turns out I get between 17 and 20 fps on in example the Shooting range mission with everything maxed out.

 

My setup is as follows:

 

AMD 955BE x4 3.2Ghz

Ati HD4890 1GB graphics

4GB DDR3 RAM

Windows 7 64-bit

1440x900 resolution

 

Is it normal to run with such low fps with a system like that?

[Migo]

Did you turn:

 

-shadows all planar

-Visib. Range = Medium

-Waterquality = Normal

 

That should help.

I was in a similar situation, with the game running poorly, even though I have a high end PC. What I did to fix it, believe it or not, is I enabled Antialiasing and Antistropic Filtering in my nVidia Control Panel. This made the game run very smooth, and increased my overall FPS quite a bit. I don't know anything about ATI cards, but I know you can force AA and AF for games with your Catalyst software.

make sure you are in full screen mode.

I understand that lowering some graphics settings should help my FPS :) What I don't understand is why it is not able to run all on high with a pretty high end system like that. I run games like ArmA 2 also high with good fps, which is also an open world persitant game with big viewdistances, lots of ai and cpu calculations etc.

Yeah, I tried those and it gives me the 17 ~ 20 fps. I'll try some different settings later today.

It's set to fullscreen :thumbup:

The graphics card doesn't play a big role here. And the Sim only uses one core, not at all but almost only one.

 

Did you install the latest patch 1.01 ?

[ZaltysZ]

Because what is considered high setting in one game, can't be taken as high in other. :) Visib. range = high isn't "high", it is more like "insane". :)

Any way I can see that? I can't remember if I installed it... The startup screen says 1.0 but it doesn't show any third number.

True. ArmA 2 has a max visible range of 10 kilometers on an island with 245 square kilometers filled with cities, villages, forests, mountains, bullet drop, gravity etc. It's considered one of the heaviest games both for GPU and CPU. But I agree, comparisons are difficult especially with different engines, different coding etc.

 

I'll stop my ArmA promotion now and focus on getting DCS to run smooth for now :music_whistling:

[Migo]

You're not able to run ArmA2 on 10km distance fluent, you ain't. Especcialy not with your 3.2Ghz Quad. When I set my CPU to 3.2Ghz I loose 30% performance (tested with ArmA2 Mark)

To run ArmA 2 very fluent, I mean minimum 50fps all the time no matter what situation. My Visib Range is 3.8km also got object details on low, shadows on normal. terrain detail on low. Now with VegetationTweak from Kju the framedrops near vegetation are gone but still you can't play on maxed out settings fluent.

 

I lowered the settings because Objectdetails on low don't look big different to very high but costs 20fps same with vegetation detail.

When I would set all settings to very high my fps would be around 30 or 40. But then still with 3.8km visib, range, with 10km it's just slideshow.

 

But that's another story. You can't tell me that you are able to run ArmA 2 maxed out fluent.

Also, don't you see any differece in flying a helicopter in ArmA 2 against DCS ?

 

You must be blind, DCS uses real physics, wind, whole calculated mechanical/electrical KA-50 system, targeting system, smart acting enemy choppers/aircrafts, you can fly up to 5000m height, map bigger then chernarus where everywhere something is going on like trains and busses, farps, bases. Also when in ArmA 2 having lot's of AI it also looses tons of FPS.

 

You can't come up with that one, but yes DCS engine isn't really based on todays hardware and capabilities.

Correct :) That's why I said "I run games like ArmA 2 also high with good fps", I never claimed to run it maxed out. Texture, postprocess, shadows etc. all high and viewdistance of 5000. Runs fluent in any community/coop mission (not campaign missions which I don't play). In the Armory I am able to set the view to 10000 but this is because there's no AI etc.

 

@DCS: I thought I read somewhere you could change a setting so it sort of makes use of more cores, but I'm not sure if I remember correctly? I'll try to turn some settings down though, to see what kind of effects they have. I don't mind how high my fps is, as long as it is fluent, which it currently isn't. Most of the time I don't see any difference if it's at least 25 ~ 30 fps. So I'm not far away from that. I'll try some tweaking tonight :)

[RealDCSpilot]

use the DCSMAX 1.7.0 launcher! it perfectly manages the cpu affinity. also defrag the HD's.

 

i'm playing with max settings, 1920x1200 resolution - quadcore 3 GHz - vista64 - 8 GB RAM and 8800 GT SLI. for every particle effect the SLI kicks in...

[Migo]

Thought since Patch 1.01 you don't need DCS Max anymore to set affinity, But great program though.

Correct.

Don't fly with water at high settings. Medium is enough. Imagine that the rendered water is all over under the terrain texture. This one setting will give you a big boost.

I thought that under Windows Vista [or 7] that multiple cores were utilized. This was why I was planning on a new i7 computer......

DOES SLI kick in? My 3 280's don't seem to make much difference. On other, true SLI games, it scales almost 1:1 in performance and makes a HUGE difference.

 

-Doc

 

EDIT: I've also noticed that moving down to 1920x1200 makes little difference.

[Migo]

For best DCS performance I would recommend a high clocked dualcore like E8400/E8500/E8600 get a nice CPU cooler and OC it. That will give you best results.

 

@Caliban

 

Like I said graphics card doesn't play a big role. It's very hard for me to get one single GTX280 fully used. You have to set AA to 16xQ with SSAA and texturefilteringquality to very high.

But this all doesn't make a difference in it's look. So to play DCS with full details you only need a 8600gt, maybe even 7600gt when playing at small resolution.

 

The rest depends on CPU clock.

[Doc. Caliban]

I OC'd my i7 920 to 3.6 just for this game. No other title benefits from the bump.

 

Oh well.

Have to agree, unfortunatley like most FS platforms the Gpu is not being used properly (why is this, development costs?) and it all comes down to the CPU and its clock..

[manne]

Well I got some better performance now with settings:

 

visible range > medium

shadows > all planar

rest > high

 

and updated to 1.0.1b and using DCSMAX 1.7

 

About ~25fps

[Doc. Caliban]

The only time I really seem to take a big hit is around buildings of any number.

[RealDCSpilot]

without dcsmax on ver 1.0.1. i recognize some kind of short fps drops. with dcsmax this is not the case.

Why are you so stubborn? Or maybe you have overlooked my earlier post? Set water to medium please. And all rest on high - even visble range or shadows.

Ah, I must have missed that one :) I'll try it out with medium water, thanks for the suggestion :thumbup:

[T.Goat]

You should be able to overclock your CPU to at least 3.6 pretty easily. Should give another boost.
