GTX Titan X Tests

[SharpeXB]

Some tests running the GTX Titan X in DCS

 

All High Settings 2xAA Vsync off

Single monitor 3840x2160

 

FC3 Blockade on the Ramp

Min 20 Max 129 Avg 36

 

Fw-190 Dogfight with the Red Tails

Min 29 Max 129 Avg 65

 

A-10C Surrounded

Min 39 Max 129 Avg 66

How were you conducting the test ?

[rcjonessnp175]

Yup goes to show ya that even with an uber duber card you cant maintain a solid frame rate in dcs world. Needs more cow bell in the cpu department. Will be interesting if you do the same tests when dcs 2.0 comes out. I suspect similar results.:cry:

Interesting. Your getting a a higher Max FPS but lower min FPS than I am with SLI Gtx 970s at 4K..

Maybe that ED should include a benchmark in DCSW 2.0, so that we can measure which system suits best to it.

Looks like you've got a stronger CPU. I'm sure that's why.

 

These are the results I got with 2x GTX 980s in SLI. Although I was running a single card, I'm not sure if there's a benefit to running SLI on a single monitor in DCS. Do you see a boost running both?

I see a pretty significant boost 35-40% Running SLI with the GTX 970. It was very finicky to setup. I ran into problem after problem running 4K @60Hz with HDMI 2.0 to HDMI 2.0 on my Vizio 4K. Did some reading and discovered it was a known issue at Nvidia. One of the suggestions as to set the refresh at 59Hz. I tried that and it works perfectly.

Well the sad truth is it really takes two Titan X cards to run most games at 4K and Ultra settings. DCS at least seems to perform well with only one

So here's some tests with the Titans in SLI running exactly the same replay tracks in DCS

 

All High Settings 2xAA Vsync off

Single monitor 3840x2160

 

A-10C Surrounded

SLI

Min 26 Max 134 Avg 70

 

Single GPU

Min 37 Max 121 Avg 60

 

Su-27 Blockade Ramp

SLI

Min 14 Max 138 Avg 30

 

Single GPU

Min 20 Max 123 Avg 39

 

On the worst case Blockade scenario the single GPU actually performs better. In the A-10 mission the average is lower although still 60fps but the minimum is higher. Plus the SLI bug on the mirrors is gone

 

So with DCS then the best route for the Titan X seems to be run single GPU

Su-27 Blockade Ramp, A-10C Surrounded, Fw-190 Dogfight with the Red Tails

 

where i can find that scenarios for FPS test? Can you describe in detail the methodology of the test?

[Gladman]

I run 5760x1080 and get results the same as GreekBull outlines with my sli GTX780's. I think I've seen a max around 114 and a min around 20-25 but average around the 45 mark lower to the ground and 75 up around 15k. I'm also running a 4790k.

It would seem the software needs to catch up to the hardware when taking the Titan into consideration.

It's a stock mission for Flaming Cliffs 3. Just sit on the ramp in the Su27 cockpit and turn your head right and left repeatedly. It's the worst FPS I can find and easily repeat in DCS

 

I can't quite tell if replay tracks perform exactly the same as live gameplay. The A-10 Surrounded in the first post is live with an Avg of 66 and the replay track is actually lower at 60. I would expect replays if anything to be higher. Many games I can recall being able to run them smoother at higher settings in replay.

Wow there's a big difference between SLI and single in the P-51D

Quick Mission circuit, all High settings, AA 2x 3840x2160

 

Single GPU

Min 32 Max 119 Avg 43

 

SLI

Min 20 Max 131 Avg 33

 

So in this case SLI is very much worse with the Titan X than running a single card

Set refresh rate to 59 instead of 60. On a side note when I do dsr 4k performance is horrible in sli think its a major bug with dcs world and nvidia drivers

[SkateZilla]

nVidia is just now getting around to paying attention to flight sims....

 

hopefully a DCS Profile makes it way into one of the future drivers.

 

Can't say the same for AMD.

Where did you hear that?

I second that???

IMO I tried DSR and it's not worth the performance hit. Asking your machine to do 4K and display it at 1080p. The effect is negligible and the performance loss too great. With SLI 980s you can run DCS maxed with 8q AA and it looks and runs much better.

Thanks for testing and posting. I would like to ask a favour. Can you test to see VRAM requirements at 4K? Im interested to see how much is needed for DCS for High settings, at least 2xAA and maybe a few texture/detail mods.

They are about to put out drivers with Game Profiles for P3D and FSX w/ DX10 Patch, and another.

[SharpeXB]

I take back what I said about running SLI. Maybe a driver update has changed something but I ran a mission yesterday in the A-10C that normally was a demanding one and it ran very smooth on both cards. It keeps the temp down too.

[jvanhoog]

I have noticed something different with sli lately as well. Running gtx780ti x 2.

[SharpeXB]

I ran a Display Driver Uninstaller and I think I get better performance running SLI now, it seems to work very well now. One important thing I realized was to set the cockpit displays to "every frame" to eliminate the flicker in the mirrors.
