AMD Ryzen - Games in 1080p can improve more than 35% !

[kladzen]

Okay.. back at it again with some ryzen news... yet again i was looking into ryzen overclocking videos.. when i came across this from amd's own site!

 

https://community.amd.com/community/gaming/blog/2017/03/14/tips-for-building-a-better-amd-ryzen-system

 

Basicly it's about how to optimize your build.. but also states some of the issues that will be fixed with patches down the road.. However the interesting part of this was the game optimization!

 

The game tested was "F1" racing game and how correct optimization is important.. So the game creates a file explaining what hardware the computer has, cpu/threads and so on.. this gets sync via steam cloud and re-synced to another computer if you reinstall the game.. Now the issue is if you have installed this on a 4core/4t CPU in the first place.. the game on a ryzen build will not notice its a 8c/16t cpu!... but rather the old 4C/4T due to the resync gamefiles... If fixing the resync game files (etc deleting them) the game then thinks its a 16 phycical core cpu... However this can also be fixed.. as this is a 8C/16T cpu.. not a 16 core cpu  Now manually editing the game file to correctly look at a 8C/16T CPU the game gains even more performance..

 

a wooping 35.53% more performance in 1080P gaming!  From 98.5 fps to 133.5 FPS - Now this just shows how important game optimization is... F1 is not the only game saving files about hardware setup, alot of games do! So getting game optimization is VERY important! And just shows that the "1080p gaming" issues might not even be relevant when game developers fix their games!

nice find, id like to see it verified by someone other than AMD though

[suicidalfranco]

brace yourselves, a LTT flame war is coming 

[Brooksie359]

I'd be more concerned with the performance improvements going from the 16 core recognition to the 8c/16t recognition by the game as that's the most likely senerio for someone who is building a Ryzen build or even benchmarking.

That sounds like really shitty coding on the developers side.

So devs are to build games for the future hardware that is not available to them? 

 

Anyways, give Ryzen some time to mature as there might be some nice surprises.

this isn't isolated to ryzen, devs know people use cloud backup and such, they should write hardwaredetection with that in mind. I don't blame them for the logical cores vs physical cores problem but this hardware detection is just broken via steam.

"Reused OS Install"
That's a big no no you don't wan't to use the same OS install across different architectures as there may be driver issues. This doesn't really isolate whether it's the games fault or the OS's fault.

I figured the software was having an issue detecting that half of the threads were "virtual" because it was not developed for AMD's SMT feature.  Does Intel have this same issue with HT?

 

I know the storing of the incidental four core CPU should change if the CPU were to change, I 100% agree with you on that.

what is this shit!?!? overclocking increases your performance!?!? who knew .... 

jeez H christ AMD are getting desperate

 

and the company that helped create HPET to recommend disabling it .. what the actual fuck!?

not even considering disabling HPET creates it's own problems

[Megah3rtz]

 More cores is a step in a good direction as long as people utilize it, heres hoping.

I actually read it, did you?!

 

next thing you're gonna tell me is that all cores OC doesn't mean all cores overclocked 

 

Quote

Overclocking memory will void any applicable AMD product warranty, even if such overclocking is enabled via AMD hardware and/or software.

 

[samcool55]

Well this is a nice challenge for LMG, take what AMD did and do the same thing and see how the results are.

Clearly not 

 

Anyway the only problem with this is it is rather likely most other games do not do hardware detection in this way, which is not at all a good way to do it so the improvement is currently isolated to this one game. Also looking at the numbers it's actually a 19.6% improvement between reusing an OS install (balanced power plan) and game install versus a clean install of both (high performance power plan), overclocking the CPU is extra on top of that but isn't really representative of the actual point.

 

The power plan difference also throws off all the numbers too so yea... bad testing methodology.

 

Also how many reviewers used existing OS install versus clean install, I have no idea but we would hope all used clean installs due to the new architecture. Going with the clean install assumption all the reviews should have accurate performance results so nothing is going to change there, games that implement similar hardware profiling should be retested with clean installs and new settings.

I'm more surprised they managed to get a Windows to still work from such a major platform switch (I can understand same mobo, different CPU, but different brand is really hard to see working well). I'd hope anyone reasonable would realize not clean installing windows is a bad idea.

 

I'm still not convinced that some games when installed are hard set in stone to that processor layout. It would be a programming fail if that were the case (But by the recent trend of some games, that wouldn't surprise me...).

 

So in total the real gain is 1% (Assuming clean install to HPET On / High Perf plan)...I don't count overclocking (enabling higher speed ram / CPU overclock) as a optimization issue since overclocking boosts everything, regardless of platform.

 

Also, curious, what if you set the game to be for 8 cores and put it on a 7700K (Go from Ryzen to 7700K)? Would it cause slow downs?

And what if you had a game installed on a 7700K (according to AMD, 4C / 4T) and also moved it over to something like a 6900K? Would it see the same slow down?

I think that many reviewers keep their games on dedicated SSD and just switch it between PCs.

Imagine how much more time it would take to benchmark everything if they had to do a clean install of every single game on every single system.

And I agree with this game being in minority of games that actually benefit from this.

it's quite common for games / software to create a settings file based on the hardware it discovers

it's the same idea behind why you should reinstall Windows if you switch platform

Cherry pick, cherry pick, cherry pick. 

Love AMD's marketing team

Oh, very interesting. (I'm not much of a gamer so I haven't noticed).

 

I guess I still have a ways to go on learning programming then.

even when changing video cards trough generations it's best to delete all game files since it's most likely the shaders will remain compiled for the old card
