E490 abysmal performance

2019-03-15, 23:32 PM

I'll preface this by admitting that I shouldn't be using a thinkpad as a gaming machine.

 

I recently got my new E490 with an i7 8565u and RX 550X, 8GB RAM. Now I'm using it mainy as a productivity machine and it's pretty solid, however I'd like to do some light gaming and graphics work (design, art, etc), hence the upgrade to the RX 550X.

 

Now this is where it gets really hard to understand - in-game (very light gaming, 2D games and pixel stuff, low system requirements) I'm getting shocking performance after about 30seconds of launching the application. It starts at a solid 60fps (locked) but quickly drops to about 5fps. Doesn't matter which game I try, they all behave the same.

 

I assumed it was thermal throttling, but the CPU and GPU temperatures appear perfectly reasonable and the clocks aren't dropping either. Here's a screenshot of what happens when in-game:

 

 

As you can see, CPU usage, clocks and temps are fine, GPU temps are actually good, but what seems strange is the GPU usage. I've set the high performance in Radeon settings, and even the Intel graphics wouldn't perform this badly. When I let the integrated graphics work, I get the same result as well (plumetting framerates). I'm stumped... I've seen throttling before but it was clear to monitor it, whereas this is confusing me. It's plugged into power source while testing, all drivers up-to-date. The laptop is only a few days old.

 

Is there something I'm doing wrong or do I need to return the device?

So, a development: toggling the power settings (using the battery icon in taskbar) fixes the issue! I think it's thermal related but not necessarily thermal throttling, rather a TDP throttling that I've read about, kicking in when it gets to about 70 - 80c.

 

For some reason, the thermals are over 10c cooler if I simply toggle the battery setting from the middle to 'best performance' and back. Works absolutely fine. Restarting the laptop brings the issue back, however. I can reproduce this every restart.

 

Is there some sort of Lenovo service that gets shutdown when cycling power options through windows? I read something about a service called Lenovo Intelligent Thermal Solution Service, and apparently disabling that can help, but toggling the power options didn't shut down this service.

 

Any ideas to make this fix more permanent or as to why this would be a fix at all?

 

You can see below that it was running warmer after a restart (start of graphs), then I toggled the battery performance option and doing the same task (gaming) resulted in lower temperatures and stable framerates. Also worth noting is the GPU1 (radeon rx 550x) usage plumetted during the warmer period. Maybe this can lend some insight into what's going on?

I have the same problem. When playing csgo i get lags/freezes every 5 seconds. Really disappointed. I read in a different thread that it has something to do with a newer bios version that throttels the gpu resulting performance that is just slightly better than that of the integrated gpu.

 

Tell me if you find a fix!

Best regards

I seem to be having the same problem. I just bought mine yesterday, with the same specs. I installed League on my laptop and tried Classic but I didnt get to play as my FPS is at 00-30 and not consistent (always dropping).

 

I am also having problems with blurry texts. I dodnt know how to fix it. I tried adjusting the scale to 100% but everything is to small for me. So for now I am just tolerating some blurred/fuzzy texts.

 

I've been looking for answers everywhere but I couldnt find soemthing helpful.

Hi. I seem to have found ta solution for this fps drops and issues on audio while gaming. The problem is in the AMD GPU. I tried disabling it when I play and the games run smoothly. It's not a good thing though because I paid extra money for this AMD GPU variant. I hope they give driver updates so that it'll run smoothly.

I'm experiencing the same issue here. I just purchased an E490, Core i5(8265U) with 16GB of RAM and AMD Radeon RX550X. I'm not a gamer but once in a while id like to just play a light game like Everspace etc but the FPS just keeps dropping, it stutters while playing and it's very annoying. I dont know where the issue is but i expect a dedicated graphics card to perform well at least with these mild games. LENOVO, please help us with this issue.
