MSI Afterburner, Furmark and TF2 not detecting Radeon 8750M

I've activated the unofficial overclocking in MSI Afterburner and set the MSI, Furmark and TF2 to high performance in the switchable graphics menu.

Yet Furmark only detects Intel's IGP and TF2 runs about the same as my old laptop with the Radeon 5730M (about the same performance of Intel 4000). MSI doesn't seem to detect the Catalyst 14.12 Omega driver.

 

TF2 runs well on my 8750m. Recognized without a problem on first launch. Newest Omega driver

 

Is it normal for TF2 to run at around 20-30 FPS at 1080p with other low-medium graphic settings and no AA on the 8750M? CPU load was less than 50% while GPU was at full load.

On a side note, I managed to get MSI Afterburner and Furmark to properly load by firing up TF2 first to activate the 8750M. I overclocked the memory from 900 to 971 MHz and core from 825 to 905 MHz. Beyond that, Furmark's benchmark score start to decrease as I increase the overclock.

EDIT: RadeonPro isn't working either. It keeps reporting, "AMD adl library could not be initialized" and then afterwards, all of the options would be grayed out.

 

I run my card at 1000/1000 and playing TF2 on 720p giving me 100+ fps all the time. (mixed settings, some maxed some on high)

 

I have used Saphire Trixx which is designed for AMD cards for OCing.. Also, TF2 should recognise and use the AMD GPU if you have installed drivers properly..

Firstly, uninstall all Intel/AMD drivers using Display Driver Uninstaller (DDU)..
Then download and install Intel drivers for your GPU from Intel Website... Remember to disable driver signature enforcement before doing this..
Then restart, disable driver signature enforcement again and install 14.12 from there: AMD Catalyst 14.12 Omega WHQL (14.501.1003.0 November 20) - Guru3D.com Forums

Should work after...

 

After additional TF2 playing and running Furmark, I noticed that Intel's XTU reported that the IGP's TDP was at 0W, 600 MHz and was at 0 voltage.

I'm still trying to figure out why Furmark doesn't recognize the Radeon 8750M and why TF2 runs so slow when Intel's IGP isn't being used.

 

Uninstall all AMD and Intel Graphics driver, then install the one that is provided for your laptop. Then simply install the Omega driver on top of it. It should work this way. (atleast its working for me...)

 

So should I get the graphic drivers from Intel's and AMD's websites? Acer's download page list drivers from last year and I doubt they'll update them.

EDIT: RadeonPro also gives me the error message of "Amd adl library could not be initialized" and all of the options are grayed out.

 

Uninstall every graphics driver then let the windows update the intel one, then install the original one from Acers webpage then install the Omega on top of it. Then it should work. I always update AMD cards this way. Once the newest is up and running then you can only update everytime when a new driver comes out.

 

Reinstalled both Intel and AMD graphic drivers. TF2 still runs slow (around 30 FPS at 1080p with no AA and low-medium graphic settings) and Furmark thinks the GPU is Intel's IGP.

RadeonPro won't run either.

 

Sorry to hear that. Can you make a GPU-Z screenshot on the AMD card?

 

This is right after I started up TF2.



I've also ran TF2 at 768p, and somehow I'm getting a similar FPS as my previous laptop's Radeon 5730M.

I'm pretty sure there's suppose to be a large performance difference between the 7750M/8750M and the 5730M...

 

There should be a large difference... I think something is not right with your GPU.. You really should remove all drivers using DDU, install Intel ones and then AMD ones... It's kind off strange as drivers seem to be installed and your card is not detected.. worst case, it might be dead but then again your drivers wouldn't install if it was...

 

I just reinstalled the Intel and AMD drivers yesterday after using Window's uninstall function.

Should I reinstall AMD's driver again, this time using DDU?

 

Uninstalled Intel's driver and OCed the 8750M from 901/971 to 1000 MHz core and memory (max GPU temp was 64C, GPUZ didn't register any throttling).

And yet no noticeable effects on the FPS. It got down to 20 FPS at 1600x900 resolution with no AA on one of the maps at 99% GPU load.

I'm still fuming that my current laptop is performing almost like my 5 years old laptop despite having technically more powerful components...

 

There's something wrong. At that level of OC the game should flow at even max details.

 

Hey what CPU do u have? is it a ULV one? It could be throttling and killing your fps! what are your CPU temps? Monitor it with XTU or HWinfo 64..

 

Could you run 3DMark demo or some other benchmark tool to get a GPU score? I want to make sure that my 8750M isn't under-performing for some reason.

It's also been difficult to test the OC stability because it would always throttle to 775/900 when running Furmark, but stayed at 1000/1000 for TF2, Civ BE demo and 3DMark demo.

It's an i7-4500U. I undervolted and it only reached a max of 70C when running with the OCed 8750M.

XTU reported that the CPU was running at 20% to 40% load. RadeonPro reported that the GPU was always at 99% load when I was running TF2. Even if it was throttling, the GPU is still apparently the bottleneck.

 

I think the CPU is the problem.. Try using throttlestop and get the turbo boost clock up as high as possible by disabling BD Prodct thing or whatever.. Your CPU is massively bottlenecking because it's usage is so low... Also get a cooler/repaste and lower temps to prevent thermal throttling...

 

I've looked at XTU and it indicated no clock rate drops. It always hovered around 2.8 to 3.0 GHz. I also bumped up the GPU's clock rate to 1000/1065 core/memory.

Oh, and I also figured out why TF2 was running like crap. The morphological anti-aliasing was causing the FPS (at 1080p) to drop from 60 (at 65% to 90% GPU load) to 10-15 FPS at 99% GPU load. That's a nearly 90% performance penalty by having that one AA feature activated.

Note to self: TF2 does not like MLAA.

 

Haha good your figured it out... Use another type of AA to fix this now

 

LOL wut?! MLAA is a post AA like FXAA, has basically zero performance impact. I've used it on 5870M, 5870, 6950, and 7950 cards with no issues whatsoever, including TF2. Are you sure you didn't confuse it with SSAA? That would slaughter performance, especially on an 8750M. Your driver installation must be messed up or something if MLAA is reducing performance so drastically.

 

No, I swear, all I did was turn off MLAA and then the FPS shot back up.

 

Amd and their weird drivers.. Hardware is great but god those drivers!

 

I wanted to play TF2 today and I experienced some terrible stuttering. A week ago it was all fine, now it dips into the 20's fps instead of the usual 120+ range... what the hekk?

 

Temperature throttling maybe of CPU or GPU? Or just the fact that source games are badly optimised and have random performance?

 

Throttle is not a thing for me. Maybe the last option... today its running 100+ fps constant

 

Source games are known for randomness .. Did you try restarting when you had these issues? I guess the restart fixed it..

 

I gave up on gaming that day and watched a movie instead. A day and 2 restarts (system updates) later, game works fine. I didn't touched anything that related to Steam or the game.

 

Should have bought a gaming laptop or anything not Samsung.. Never had these type of issues ever... I was blasting BF4 on ultra on full HD yesterday at 60fps+++...

 

Thanks. How much did your "not samsung but gaming laptop iPlay BF4 on ultramaxedout @ 100fps" cost? Budget! Mine was like 400 USD... end of topic! Someone close it.

 

Wut you got the Samsung for $400? Great deal.. Can't complain .. My Samsung ultrabook with i5-3317u, HD4000 GPU, 6GB RAM, 500GB HDD + 24GB SSD was like £600 new..

P.S: Don't ask how much I've spent on the AW.. It makes me cry
