[Archived] Performance issues on new laptop

Problem Details: I got a new laptop which on paper has a better CPU, but for some reason it has 25ms input lag and 30fps. When I tab out of the game and tab in again, I get +100 fps, and 3ms input lag, for 2 seconds, untill it goes up again.

Old cpu: 2.16ghz Dual-core 1mb cache
New cpu: 1.1ghz Quad-core 2mb cache
Resolution: is the same
gpu: it's better on the new one.

I want to know if it's because osu doesn't have quad-core support. And if that is the case, how to turn it on?



osu! version: 20170731.2 (latest)

Even though the new laptop is a quad core, it will still be slower than the other one, since each core is only working at 1.1Ghz, and since it is a laptop it might have integrated graphics, which tend to be slower than normal graphics cards.

Not to be rude, but that was quite obvious.

Like I stated earlier, on paper the quad-core is better since it also has a 2mb cache, while the other only has a 1mb cache, the dual-core doesn't even have hyper-threading. So 2 cores + 2 threads vs 4 cores + 4 threads, in this scenario the quad wins by far, unless osu doesn't support quadcore. And for the inegrated graphic cards, the quad-core laptop has a 70% better performance.

Specific specs:

n4200
vs
n2840

Side note:
The cpu isn't under pressure at all when playing osu, about 40% usage, I also tried looking at the different usage per core, and core 0 had a bit more load than the rest, but core 1-3 was running at the same.

just tbh cores and threads aren't only important in processors, clocks are important too...

If you could tell us what GPU you have now and what GPU you had, it would help. But if you dont have the old laptop and dont remember the GPU name then just the new would would suffice.

I know, but with side by the N4200 still stomps with it's more cores, which is why I need to know if it has something to do with osu not support 4 cores. hell, it even is better with single cores on the benchmarks.

but benchmark are using all cores, in game almost always clock > cores

Osu! supports 4 cores, i know because i have a quad core and it works perfectly.

Okay so I figured out the problem, and no one was remotely close. Though the suggestion were appreciated, none of you seemed to have understood what I meant, which is understandable.

I was running at "low performance mode" since I had power save enabled. I solved this issue simply by putting my charger in which automatically put it on high performance which gained me the good fps and low input lag.
