So I just installed DCS world (did not use any beta) and the performance difference between A-10C 1.1.1.1 and DCS world 1.2 are both confusing and unacceptable.

 

I could run previous A-10 versions with little difficulty (it stuttered a bit on the ground) but now I notice frequent stutters while in cockpit and it slows to a unplayable slideshow when I turn on the MAV or TGP screens on the MFD's, this makes the sim unplayable for me unfortunately.

 

I am running a AMD 9950 BE x4, Geforce 9800GT, 8 gigs of ram and running the latest drivers for everything, keep in mind, I was able to run DCS A-10C very well, only minor stutters on the ground and I seriously doubt that the engine has changed enough to justify such a massive drop in performance.

 

I don't expect a immediate fix, I will be sticking with older versions until a hotfix or a patch comes out that will address these issues (it seems I am not the only one to have this problem on the forum) and I hope this is not just dismissed with "Get a better computer", I can't and won't at this time, also, I do not see anything in the updated engine that would cause this performance drop to be so dramatic.

 

anyway, my rant is over but I just wanted to post my results and possibly it will help the ED team with the (hopfully soon to be) patch.

 

 

***EDIT***

 

I have scaled down all of the settings in a attempt to increase frames but that only goes so far, I have unticked TSAA (never used it in previous versions), unticked disable aero interface (advice given on other parts of this subforum) and decreased many settings overall, still not getting adequate performance at all.

The Graphics Engine has improved to the point it requires a Video Card with at least 2Gigs of Ram.

 

 

I understand you not wanting to get a new pc over a game, in your case it is just a video card. I mean come on that 9800Gt is like 7yrs old now. that is a life time in Dog yrs. and PC yrs. Hope that releives a bit of the adimacy you have with updating the PC. 7yrs old Wow.

A 7yr. old Video Card and a newer updated graphics engine. new terrain and grass even. I wouldn't recomend anything under 2Gigs for a graphics card for use in this "Simulation of an A10 Warthog" This is not a "PC Game".

Sorry about the double post the first attempt came back as an error, then showed up anyway.

Then maybe the simulation should learn some things from PC gaming. The graphics are nowhere near good enough to justify requiring a 2GB video card. Half the time the game renders nothing but flat textures on a heightmap and little dots for aircraft.

 

Luckily, the game runs just fine with graphics cards considerably weaker than that, so you're just in this thread being useless as all hell.

Completely disagreed. 1GB RAM is quite enough, unless you're running huge resolutions or multi-monitor setups like Eyefinity.

I am sorry, I don't buy that at all.

 

The fact that I was able to run this sim with my card before is a good indication that I should be able to run it still, I don't see where I would need a 2 gig card.

 

Also, I can't afford a new card so acting like I can just go out and buy a 2 gig card (and insulting the quality of my current rig) is really kinda rude.

 

You are more than welcome to buy me a better card if you seem to think it is so easy to afford (I am unemployed and stuck in the state with nearly the worst unemployment in the country).

1080 and multi monitors are more the standard now. so yes. and the price of tv 32" and higher are dropping everyday.

 

Looking through the post of people with problems, 1G cards require tweeking. 2Gigs and I have everything on high with long distande tree and bushes. birds and all. TSAA and Q 16 just because I can. It also allows for longer Video card life basedon A10 updates a yrs from now will you think 1Gig is good enough for this sim? probably not best to be safe.

 

It is based on that that I "Recomend" 2Gig, I did not say it was required. Just allows for fewer head aches and little in the way of tweeking.

LOL! There are no birds in this game.

 

The 'birds' setting is just a prevalence of birdstrike failure.

 

Yes we all are aware of what it is.....Don't miss the point while you attempt to make someone look bad. It has been know to backfire. Read my point again I think you missed something.

I run the sim at 1280-1204 on a 17 inch monitor, I don't think I am running some sort of extreme resolution, the performance simply should be better.

 

That said, the minimum requirements have not changed between DCS A-10C 1.1.1.1 and DCS world 1.2, I suspect that there is a optimization problem for some cards or something because the performance hit only really happens when I turn on the TGP or the MAV, any other time and it is smooth as butter.

 

Something is not right and it is not the fact that I am not running with a 2gig card.

Just to add a datapoint: I fly with Mike frequently, and we were flying a mission when he encountered the problems he's reporting.

 

My rig is a Macbook Pro (ya rly) with a bunch of external hardware connected.

 

Core i7 2.6 ghz; 8gb PC8500 RAM; GeForce 330M 512mb VRAM; 1920x1200 display

 

All my graphics settings are at LOW; Cockpit Displays at 512; Disable Aero enabled; Clutter/Bushes at 0m; Trees at 1500m; Preload Radius at 150000m; all checkboxes disabled except "Disable Aero" and "Fullscreen.

 

I am getting acceptable framerates with both the Shark and the Hawg and I did not notice a major hit between 1.1.1.1 and 1.2.0. Nobody's going to confuse my rig for a gaming machine, but I can fly. Not sure what's up on Mike's end, but his specs aren't that much lower than mine, so I'm not sure what's going on there. I don't think it's just the lower-grade GPU, though...

I do not completely disagree with you, and of course we are talking "Hypothosys" based on PC experience of over 20yrs. now.

 

I stated 2Gig Video Card and should have went into detail. My thoughts are based on CUDA and C\C++ added to the newer cards PhysX and Pure VideoHD. And my statement of just all 2Gig cards in a description is grounded in those technologys.

 

But if you are insisting that it is system based (and you of course know best) then I would look to cache and defragmenting. These are of course base intigers and one of your experience most likely have tried these?

 

Barring those a full HDD and back ground programs could be the culprit.

I have recently defragged, I run very, very few background programs (just steam, freetrack and teamspeak, everything else is basic system stuff).

 

The thing is, I can't seem to nail down this problem at all, performance never seems to increase even when I lower the settings in game, I have already turned many things off or switched them to "application controlled" in my Nvidia control panel.

 

I am not talking about a small framerate hit between A-10C 1.1.1.1 and DCS world, I am talking about the difference between running very smooth (no real framerate issues at all once in the air and expected framerate hits on the ground) to a unplayable slideshow, this makes no sense unless they have upped the overall texture resolution on _everything_ in the sim.

 

So, I have tried everything that I can do on my end and it seems that my dreams of flying the upcoming DCS Mig-21 Fishbed (my favorite aircraft in the world) are dashed because of either a bug or something else.

 

Looks like I will be hanging up my wings until I can either, A.) Download a patch or hotfix that may or may not come in the future and might not even address my issue (and the issue that others seem to be having also!) or just hope that I can someday buy new parts in the hope that they will make the a difference.

 

I doubt I will be buying new parts any time soon though.

 

 

C'mon ED, you gotta know t his is going on!

I didn't see it mentioned anywhere but, if you're using 1024 resolution of cockpit displays, or even worse, 1024 every frame, try reducing it to 512 or 256. Generally, I don't think it's a good idea to use 1024 res cockpit displays unless you have a very good computer. 512 res displays still look pretty good, and are MUCH less resource-hungry. 256 res displays are even less resource-hungry of course, but they can look kinda bad.

 

Also, if you are getting really horrible frame rates in a specific mission, see if there are any AI aircraft. There is an issue with 1.2.0 where AI aircraft formations flying over specific areas at slow speeds can massively reduce the frame rate, so you want to be on the look out for that.
