Can we talk sim racing performance with the 8k?

Pimax 8K Series

Superposition.

Here is a custom VR Ready run.

Good score, red feller.

Thanks Front. 75 to 80 with normal FOV is encouraging. When it goes below 80 does it get jumpy and jittery like my Vive does when it drops below 90? Did you have 10-15 cars on the grid?

Ughā€¦ just saw that you have a 2080ti so that sets me a little below your specs. Still hoping some 1080ti guys will respond.

Thanks for starting this thread. I too was curious as to how the Pimaxā€¦particularly the 5K+ā€¦runs racing sims such as AC, PCars 2 and IRacing. I have a 1080ti and I think I might go ahead and just sell it and upgrade to a 2080TI.

Iā€™m anxiously waiting for more impressions from 5K+ users to keep 'em coming guys :slight_smile:

1080ti and Project cars 2 runs pretty good with default supersampling and low-middle ingame settings. Didnt noticed any issues, i suppose its possible to tune up some settings or supersample a bit.

what FOV option are you using?

27

Thanks a lot for the benchmark score. My 4770k with 1080Ti give similar but slight better score and fps. Do you happen to have AC or iRacing you can test with 5k+? Just wondering what kind of fps you can get.

28

Unfortunately no I do not.

But 5k+ & 8k perform similar.

29

After using UserBenchmark repeatedly, Iā€™ve been able to tweak my CPU and Memory speeds to get a much better score. I like this utility a lot.

UserBenchmarks: Game 143%, Desk 153%, Work 140%
CPU: Intel Core i7-8700K - 126.6%
GPU: Nvidia RTX 2080 - 165.4%
SSD: WD Black NVMe PCIe M.2 1TB (2018) - 289.7%
SSD: WD Blue 3D 1TB - 112.5%
RAM: G.SKILL F4 DDR4 3600 C19 2x8GB - 105.8%

Now Iā€™ll test in in Elite Dangerous, to see if itā€™s truly stable.

[update] It seems stable, after 15 minutes of play.

I find elite crashes a lot if I over clock to much :frowning_face:

Then Your overclock isnā€™t stable. Itā€™s not EDā€™s faultā€¦ :wink:

I can run iracing full settings and 130% steam vr SS with 5k+ (4670k at 4.8 Ghz, 2080 Ti at 2085 Mhz) in practices with a steady 90 fpsā€¦ But in real races on some tracks it is hovering around 75 fps, no matter if I move to lower settings or back up on the SS.
fpsVR shows GPU around 70%, I think I am being CPU limited in some scenarios (no surprises really, just waiting for Zen 2)

Normal fov, obviously, forget about other optionsšŸ˜

based on blue room scores. you are look at probably ~6~10% performance with better CPU
The best scores are all 2x2080TI + 7980XE

When I look into details I can see PiTool and Steam VR are using quite a bit of CPU themselves, so I am wondering if getting into that silly core count race would not give quite a bit more performance, at least more than theoric isolated benchmarks where only the games are running on the OS.
I have been a professional reviewer for a few years on a french website, I know how we deal with this. We all bench with clean OS and NO other programs running. Real story is a bit different.

Already using normal FOV of course.
Just a matter of weeks before going 8 cores @ 5 Ghz anyway, weā€™ll see

howā€™s your CPU load during race in iRacing? fpsVR can show that right? (although during blue room my CPU load is very low so I dont know in what aspect can better CPU help VR at least in the case of blue room, itā€™s not like there is a lot of physics to be calculated)

Itā€™s around 80%, but not sure how it calculates.
If some threads are loaded at 100% I can still be CPU limited that way

Havenā€™t yet found the time to test further

my guess is with a card like 2080Ti CPU threads count matters moreā€¦

Guys, I appreciate the replies related to the the 5k+ but in the OP Iā€™m asking specifically for 8k performance. Itā€™s a given that the 5k+ presents a lighter burden on the graphics even though it runs at 90hz. And with the lower FPS option promised by Pimax I have no doubt that the 5k+ will be the fall-back if the 8k canā€™t cut it with my 1080ti.

So please stick to the 8k. If you have rF2 or PC2 installed then please give me some feedback on those sims with the 8k. (Helios? Ludx? mr.uu?)
And while all the blueroom scores, bottleneck stats and Elite performance are interesting in themselves, without addressing the specific question of 8k performance with a 1080ti they sort of dilute the thread.

Editing the thread title again.

Elite did not crash for me, but 3DMark did, during the CPU test. I backed off the CPU overclock (slightly) and now 3DMark no longer crashes. Iā€™m pretty happy with my system now. Itā€™s performing great. One of the big improvements is that my boot ā€œdiskā€ is a 1TB NVMe SSD, which is 6 times faster than my main SATA SSD.

Hereā€™s a link to it, in case anyone is interested: WD Black NVMe M.2 2280 1TB PCI-Express 3.0 x4 3D NAND Internal Solid State Drive (SSD) WDS100T2X0C - Newegg.com

I will be getting an 8K (backer # 31xx). My 2080 is roughly equivalent to a 1080Ti. Iā€™ll be sure to post my impressions, but it will be a while.
