Dota 2 Receives Optimization For AMD Ryzen CPUs

Though I don't play DOTA2 and likely never will, I am still interested in these results. DOTA2 will be the first commercial example in years of what happens when you tweak software for a specific CPU architecture. To me, that's very interesting. Mind keeping us posted if Michael won't?

I diddn't save the run pre dota update, but i have a run @1440p with GTX1070, Ryzen 1800X @stock (mem:3200mhz CL16) vs FX-8320 @4.6Ghz
Ryzen after dota update and FX pre.

Yeah, I'll start my tests with it and have some results this evening.

Here is the after: http://openbenchmarking.org/result/1...TA-RYZENDOTA62

It made a pretty fucking big improvement. Went from 67 FPS before to 108 FPS after...

Wow! Thanks a lot for posting the results. This is very critical information, because it shows how much a little bit of optimization can make all the difference. It didn't seem to take Valve very long to release these patches either, so clearly it wasn't too difficult for them to accomplish this. All that being said, when you consider the performance of Ryzen without any optimizations, it fares modestly well.

This gives me hope that Ryzen will really shape up into something very nice.

Going to have to call this out as deceptive benchmarks are a pet peeve of mine.

Look, no gamer plays at 800x600 resolution with vsync off. Obviously any such benchmark would be entirely CPU bottlenecked and your results severely exaggerate the performance gains. If any, the overwhelming majority of users will get while playing the game. Redo at 1920x1080 with vsync on.

It's a CPU benchmark - you want to use lower resolutions, to eliminate any other bottlenecks. This is exactly why people were whining about Ryzen in the first place - at 2K and 4K resolutions, the gaming performance in fine, but at 1080p its noticeably worse.

As long as both the before and after results are 800x600, how is this situation any different?

Actually low resolution benchmarks are more of a RAM clock speed benchmark than anything. When you do artificial benchmarks like that you create bottlenecks that would not occur in real world scenarios. If he over clocks his RAM and runs that same benchmark, he will see significant FPS gains but in the real world, RAM would never be a bottleneck and only comes into play at FPS above 80.

Michael could you do a test of the new Dota2 with the 1800x and the 7700k ? We could then "manually" confront it with this
