DCS World: ATI R9270X 2GB vs NVidia GTX650Ti Boost 2GB

[Pavel A]

Have two cards at home, so performed small test of $250 ATI R9270X vs $150 NVidia GTX650TiBoost.

Result shows that code is clearly not optimized for ATI ))

 

1920x1200

 

Ka50 free flight:

ATI ~30 - 32 FPS

Nvidia ~38 FPS

 

Mi8 take off:

ATI ~17 - 20 FPS

Nvidia ~27-28 FPS

 

DCS World version 1.2.6, videocards drivers are latest (archive names are AMD_13101_78, nvidia_31416)

Hope it can be usefull for those looking for new videocard for DCS (btw, in FSX similar picture, but gap is not that big)

Some screenshots attached.

 

brief PC config:

MB: Asus P8H67I delux

CPU: Intel i5 2500

Memory: DDR3 8GB

video settings attached, overall med to high

Why would you imagine that ED does optimizations for specific brand at all?

In general, it was reported on forums that DCS runs very bad even on R290, probably because it is still DirectX9 and AMD don't optimize drivers for it already, so I'm afraid that's life we are living in.

well, I just mean that it runs poorly on ATI cards and even lower Nvidia card is performing better. Sorry if I suddenly confused you.

AMD/ATI drivers... not DCS.

 

I feel your pain, (I'm using an HD7870). The card works awesome with DirectX11 games.

Known facts.

Long time ATI sufferer here, the cards are not optimised for DirectX9 so we have to wait for EDGE

 

Depending on how it performs will decide if I go to NVIDIA. ( I want to stay with ATI :) )

should be a sticky somewhere. :) seems there's an AMD/ATI FPS posting every other day.

The idea that poor DCS performance is down to AMD drivers is pure BS to be frank. There are dozens of DX9 games where modern AMD GPUs outperform or match Nvidia cards.

 

The fact is DCS is just poorly optimised. The fact I get identical framerate with my R9 290X at low res and low setting compared to high res 2560x1600 and maximum settings points to game problem, not driver problems.

 

Skyrim DX9 is as fast on R9 290 vs Titan

Or how about HD 780 in Witcher 2 DX9. Note how HD780 beats GTX580 or HD6970 comes close to GTX580. No problems with AMD and DX9 there.

AMD cards have zero problems with other games on DX9. It's a 100% DCS problem, not AMDs. So this claim that AMD drivers are poor in DX9 compared to Nvidia and this is why DCS runs like crap on AMD are BS. Because every other DX9 benchmark I can find shows no such serious FPS issue. If these bogus claims were correct then every single DX9 game ever released would be far slower on AMD hardware than Nvidia equivalent. Funny that doesn't seem to be the case.

I saw some posts for DCS low performance with ATI, but did not find direct FPS comparison. So when I made my small research I was shocked - it can be around 50% gap vs cheaper card! Actually it is so significant so it shoudl be mentioned in game system requirements.

But I will stick for Nvidia card now. If fits better to my PC case + lower power conusmption & temerature ))

I'm wating for EDGE - and if AMD is still that much slower than Nvidia, I'll have to bite the bullet and buy a 780.

[SAM77]

Thank you for posting your results Pavel

 

I had trouble choosing between R9 270 an GTX 660 as upgrade from ATI 5770

 

So glad I bought the 660 seeing as a from your results a 650Ti beats it in DCS.

 

Sort of have mixed feelings about whether I should have gone for a 760.

 

Oh well maybe if prices come down a lil I might try Sli for once in my life

Kinda what I'm thinking too... If EDGE doesn't help on the AMD GPU front, I'll ditch and buy NV... Though I do love AMD for most other games, unfortunate they run like a dog, (when compared to NV), within DCSW.

Um, I notice that in the ATI screenshots with the lower FPS, the Render Main and Scene Objects counts were both significantly higher. My testing appears to show that the later has the most effect on framerates http://forums.eagle.ru/showpost.php?p=1996080&postcount=114

 

So it's not really a fair comparison when the number of objects being rendered isn't the same, unless somehow AMD drivers actually cause the number of objects to increase for the same scene, which seems unlikely.

A bit of a necro here, but this issue of resolution not having an effect on performance is not limited just to this newer AMD card, but older ones as well. Armed with an i7 2600K and a pair of HD7970s, I set out on a quest for 60FPS performance. While I saw a marked improvement dropping from 2560x1600, there was limited difference between 1920x1200 and 1680x1050. This tells me that DCS World is CPU-limited, which is probably no surprise to anyone here.

 

I'll address some other strategies for chasing after my performance goals in Part 2, but my initial findings are here:

DCS Doesnt support XFire, so it's pointless to have them in Xfire mode.

 

With EDGE XFire will be fully supported.
