You realize 4k is old news? Introducing...... 5K monitors!! (Graphics cards, and maybe Outerra, begin to cry)

Pretty sure 8K is the way to go...

Yet another performance benchmark, this time focusing on finding the optimal settings for model rendering (non-procedural) across different hardware. This one is testing the achievable triangle throughput and number of draw calls in several rendering modes and with varying mesh sizes.

There are 103 tests there, each taking roughly 5 seconds, so it can take 9-10 minutes total.

If you would like to help us gathering performance data, the test can be downloaded here: outerra_perf_tests.zip
Run the cubes_test.bat

Here are some results from our cards
* Nvidia cards are able to reach much higher draw call counts than AMD (40M vs 13M), apparently having a lower overhead
* newer AMD cards need larger meshes to achieve better performance (triangle throughput), 208-triangle mesh still doesn't start to saturate it
* interesting to compare the number of draw calls in this test (single-core OpenGL) with the reported number of draw calls in DX12 (13.4 Million on multiple cores)
* indirect draw is the fastest method, for some reason faster than instanced draw call that does the same thing without an extra buffer

AMD R9 380


AMD 7970 (280X)


NV 750TI


NV 960GTX


NV Titan Z

ha-ha-ha ... GTX980Ti kicks Titan Z with Score: 5332(cubes_test) .... almost by half.  :P =D ;)

p.s. DX12 I can not test because I hav Win7x64 ... and this SpamWin10 does not come to me on  HDDs ...fam. Punkt aus! :))

I think my 770 4GB got around 2500+ again.

Uploaded, this time without problems with the firewall.

Saw this post on Reddit and decided to help out.
Ran the test with a GeForce GTX 980 Ti (with 361.43 drivers) but forget what I scored. Uploaded fine though.
I might run it again a few times later with a fresh restart and less crap running in the background to see if it makes a difference...

Thought it was interesting that these drawcall tests look kind of similar visually. The results were also interesting.

Question: What does the Outerra engine think of hyperthreading?

Does it have a preference for physical over virtual CPU's in its workload?

Does it work better with just physical cores, or does it care?

I don't really have a good (measured) info about the difference in performance under different situations, just assuming that since it has to share certain critical resources like the cache, it won't work well as soon as these resources are the bottleneck. Which is often the case for high perf applications. To truly utilize hyperthreading we'd have optimize for it, which seems to a lot of work for disputable gain ...

Blog post about the grass perf test: http://outerra.blogspot.com/2016/01/procedural-rendering-performance-test-1.html

hmm ... I see there is not the GTX 980 Ti. Were not interesting for the tests?  ???

Added graphs for 980 Ti. We are still waiting for top AMD cards to show up, so the blog was another way to get more reports.
