Alienware graphics amplifier

Jump to solution

I seriously need help. I’ve been trouble shooting for over 20 hours over a couple of weeks. My AGA and computer will not run games at a high frame rate. For example Doom is almost unplayable with frame rate drops that bounce from 130-50 non stop. Bf1 will not run above ninety and will not stabilize and is constantly fluctuatiing between 90-70. Dell support has not helped me at all. They just assume I’m and **bleep** and can’t troubleshoit myself so they just tell me to reinstall graphics drivers. I don’t have time to sit around and wait all day to watch them go through the same procedures I have done ( multiple times)

Specs:

Alienware 17r4 1050ti (internal)

16 gb ram

i7 7700hq 2.8 ghz

nvidia gtx 1080 founders edition(external)

upgraded to Samsung 500 gb ssd

i know from my reasearch I can run intensive games at very high frame rates. My frame rate increase for Fortnite between the 1050 ti and 1080 was bout 20, unacceptable for how much I spent. My cpu is also working very hard and my gpu is not m.

troubleshooting steps I’ve taken-

-uninstall and reinstall all graphics drivers including intel

-updated bios

- benchamarked ( I get decent numbers on heaven extreme setting with an average 106 cpu and gpu temps are good) 

- examined multiple different NVIDIA control panel settings

...... and more

someone please help me I’ve spent over $2000 on this computer and it’s my first, and dell supports only answer is someone I can barely understand and there response is to lower my graphics settings. I was so excited to get AGA and 1080 and now it makes me sick to look at me pc because I dumped so much money into something that doesn’t function well.

Definitely not purchasing anything dell again.

Hi @Not pleased,

Connect a monitor to the amplifier.

I don't understand can you clarify. My CPU usage is high in some games what would connecting a monitor do ?

You take a performance hit when you use a graphics card installed inside the AGA to accelerate content on the built-in panel, because after sending the raw data from the system to the AGA for rendering, the rendered video frames have to come back from the AGA into the system.  The suggestion to attach a display directly to the AGA and play games on that was meant to at least test the effect of eliminating that bottleneck, because in that case, rendered video frames go straight from the AGA out to the display without having to come back across the PCIe bus into the system.

Started doing some research into this subject and thank you both so much, finally an answer. I'm a little upset I have to purchase an external monitor but I was going to eventually. Anyone reading this thread should post questions on here. Dell support would have had me return my graphics card (which I didn't want to do because I really like Best Buy Haha), and when that would not have worked I would have had to send my AGA back, with no fix. So glad this is resolved, I really appreciate this but sadly I will probably not purchase Dell in the future because there customer support is hot garbage.

Sorry you didn't get good answers from support, but in fairness you don't "have to" purchase an external display.  Doing so will increase your performance, but that doesn't mean it's required.  The performance hit you're incurring is inherent to any external GPU setup.  And not directly related, but I'm surprised you consider a drop from 130 to 50 fps to be unplayable, since 50 fps should still be plenty smooth and definitely not unplayable.  Some consoles play certain games at a constant 30 fps, and even console/game combinations designed to run at 60 fps will occasionally drop to or even below 50.  But then again I'm a casual gamer at best.  In any case, good luck with whatever setup you end up with.

This is more of an academic interest question, but it's still worth asking, in my humble opinion.

My understanding is that the link from the Laptop to the A.G.A. is 4 PCIe lanes.  Am I correct in thinking that in a situation such as this, they're effectively a half duplex link?  And if so, does that also represent a performance hit when using the A.G.A. to accelerate the built in panel?
