Hi everyone,

I noticed a strange issue the last few times I played. The CPU thread that runs IL2 is only running at around 50% of its normal clock speed, but is constantly used 80-90%. Normally hyperthreading would kick in and raise the clock speed over 4GHz, but it is only running at around 1800 MHz. Do you know a way to force that number higher? I only get around 30 fps although my setup is ok.
My specs
RX 580 8 GB
Ryzen 5 3600
16 GB 3200MHz DDR4

Thank you!

This is an old game....run on single core without hypertreading....

....my 2 cents is to enable the process affinity mask running on all physical cores only....

....but maybe some expert can help you better....

I see a lot of confusion here.
Hyperthreading has absolutely nothing to do with the CPU's clock speed.
What you're looking for is actually the boost clock.

Main line, read, listen and understand: Ryzen 3000 CPUs have issues with older games.

You will have to have a certain level of PC expertise to work your way around it.
You have to have a capable CPU cooler, otherwise Ryzen 3000 CPUs will hit their thermal limit pretty soon.
The mainboard's BIOS needs to be up to date.
The mainboard drivers need to be up to date.
PBO (Precision Boost Overdrive) can have a severe impact. Try to change it's different settings (auto/on/off/whatever) to see if it changes anything.
Many mainboard vendors provide additional tools and utilities that feature e.g. "gaming modes", where you can raise the clock rate manually.
Ryzen 3000 CPUs often cannot detect the CPU load correctly if it's on a single core only. Use said mainboard tools to raise the clock manually instead.
Make sure you're using the right tools to read the clock rate. In doubt, use AMD or mainboard manufacturer tools. HWInfo needs to support the mainboard, otherwise it will read wrong values.

Thank you both very much for your replies. Setting the process affinity seems to have helped.

I will dig into my motherboard settings more. I noticed that my boost clock rarely exceeds standard clock speeds for any game that doesn't utilize multiple cores. Might be a good idea to just overclock the CPU and see if that gives me additional FPS instead of relying on the boost clock to kick in. I have a pretty beefy cooler because I had a high overclock on my old CPU.

And sorry for the confusion, I meant the boost clock, not hyperthreading. It was late at night.

No need to overclock your CPU.
Use mainboard manufacturer tools to statically apply boost clock rates to one or more cores of your CPU instead, that should do the trick already.
Overlocking will not help at all if the CPU sees no need to enter boost clock rates, and if it does, overlocking will pretty soon get you into thermal throttling issues since Ryzens, like any AMD CPU, are hotrods.

No need to overclock your CPU.

Never forget, overclocking will kill your PC sooner or later!

But it makes your dick grow bigger, doesn't it?

Hello Mike,

I still remember the good old cheap "AMD" days, when I overcracked everything, the CPU (2200), the graphics card (Nvidia 4200) and even my "Creative" sound card (I'm a musician).

The 1200,- DM (Deutschmark    ) computer (year 2000) did not last 12 months - I then completely disposed of it.

And... I don't want to talk about my 22 cm! 


Best regards,

Gerhard
