Thoughts on 1070 FE to 1080 TI?

Curious to see your thoughts on upgrading from 1070 FE to 1080 TI. Will 3 more GB of VRAM make any difference in stutter minimization?

Just an observation with the latest updates to 2.5 I get about 8~8.5GB VRAM usage. Usage in earlier 2.5.x versions was up around 10~10.5GB however I don't notice any difference.

As far as I can tell stutters occur when the GPU hits 100% usage every time and repeatable, so I back settings off until I have an average 65~75% GPU usage (also 12~14% CPU usage) this GPU usage varies depending on map and activity however by lowering settings for me with a 1080Ti and Rift that's usually dropping the PD to 1.1~1.2 and MSAA at 2 or 4 depending on which map I fly.

I find that with PD at 1.2 and MSAA @ 4 is about the sweet spot for NTTR and if I were to fly in other maps then I will get the occasional stutter which can usually be minimised by either dropping PD to 1.1 or MASS to 2 although I don't really bother as it's only an occasional stutter say on PG or Normandy maps and very occasional in Caucasus.

Before the implementation of deferred shading I could happily get 90FPS in Rift on NTTR with my 980Ti however that is now 45FPS but solid with the 1080Ti. This indicates that it's more the GPU power of the 1080Ti being taxed.

YMMV. :thumbup:

MSAA is just absolutely bad for performance especially in DCS with deferred shading. You could probably get better results by dropping MSAA to 0 and adding a bit of PD, or using the tweak posted somewhere in the forums which applies MSAA only to a central circle (making it a lot less expensive).

Good to know! Thanks. Thinking about grabbing a 1080 TI as the price continues to drop.

where have you seend 1080ti prices dropping?

they are inreasing again.....at least on amazon....

So far it looks like the low point was perhaps the end of August. I'm hoping the prices will drop again once the RTX cards are released.

I was planning on a 1080Ti, I just wonder if I need this for non-VR and good frame rates with high settings???

I hate to break the news, but the RTX cards have been released (2080 and 2080 Ti). 2070 releasing some point in future.

reading into his question the minimization of stuttering might indicate that VRAM is the main variable due to DCS usage pattern as others have pointed out, therefore his choice of GFX should be focusing VRAM amount and not necessarily the GPU itself.

This rules out 2080 or 2070 cards as both have only 8GB but the Ti models have 11GB. Therefore its a choice between those 2.

That is correct. I wonder if the extra 3GB of VRAM will matter as FPS differences between my current 1070 vs the 1080 ti are probably not that great. Pilotasso, how do you like your 1080 ti performance running in the NTTR and PG maps? The 2080 ti just seems awful steep for the bang for the buck ratio IMHO. Unless somebody can show me blazing fast DCSW performance numbers and no stutter, the 2080 ti does not seem like a good value at this time for flight sims.

Below you can see my testing of the 1080Ti @ 1440p with a number of games and benchmarks when I changed CPU this April. In DCS I used high detail preset on the NTTR map.

You can see the results below.

Thinking about upgrading from my GTX1070 to a GTX1080ti as my current setup can only take me to pixel density 1.0 max without stuttering when flying low or looking at the cockpit edges.

Would my I5-4690K (overclocked to 4.5Ghz) be a bottleneck in my rig?

Thanks for the info! Perhaps an 11GB GPU is not that significant at the moment.

Try this shader mod, https://forums.eagle.ru/showthread.php?t=215373. I have the 1070 and can run the PD at 1.3 to 1.4, big jump in performance. Just adjust the mask size as required, you can also adjust the central area size re MSAA.

VR only? Or can it push a 55" 4K also?

VR only atm.
