Is Fortnite Laggy On Windows 10
Roseanne Devon
A few weeks ago I downloaded Unraid and started using the trail version. Setting up the storage array was easy enough and after using it for 2 weeks I felt confident enough to create a Windows 10vm and merge the Unraid system with my main system. Unraid was running on some older hardware that I had but I prefer to have one system that does everything.
Anyway after some issues with setting up the Windows vm (and getting help from the Dutch forum on tweakers.net) I now have a windows 10 vm running with GPU passthrough. The system runs and is usable but there are issues with performance. Running benchmarks is fine and even gaming works fine.
So what is the problem? Windows is slow, laggy. Draggin a window across the desktop results in stutters. This gets much much worse when copying data from an external hdd to the array. As a result the vm is not usable when it is accessing the array.
There is 1 1tb ssd that is not assigned. That ssd is used for my Windows vm. The vm also has one motherboard usb controller passed through. There is an external 10tb hdd connected to one of those usb ports.
Copying files from the external hdd connected to the Windows vm (not the copy one.) to the array runs at about 100MB a second. Even though the drives can handle 180. Copying the files back from the array to the hdd results in this 180MB speed.
For me it is not a problem if copying the data is a bit slower but when copying Windows starts to run as slow as an old Windows 3.1 machine. But even if I am not copying data it is still laggy when dragging windows or opening something. Its like I am using my windows through something like Teamviewer even though I am not.
Update: After finding some tips about threads I did some more testing. Unfortunatly it did not help. Changing the amount of cores, disabling hyperthreading or pinning did not improve the performance.
I did forget to mention that I have already installed my Windows from scratch last saturday and it is using i400fx-5.2. Should i downgrade to 4.2? I can't seem to find a list that shows me the differences between those versions. Though I also have tried 4.2 before and got the same stuttering. But I could try it again.
Just wanted to let you know that I have tried older versions of the i440. None worked better. I have been playing around with cpu isolation and pinning. It seems Unraid sometimes uses isolated cored. If Windows is also accessing them, then I get to see the lagging issues a lot more.
I ordered a Samsung 970 EVO to install my Windows VM and changed my cache drive to the old ssd that my previous (laggy) install ran on. After booting Unraid suddely can't use my second GPU. It has no hardware ID. I also had a lot of trouble getting a new VM up and running. GPU passthrough just wouldn't work. However after rebooting a couple thousand times it did work. Surprisingly my new VM is snappy. There is no lag. So problem solved right? Nope.
My new VM does stutter when DisplayFusion is running. If I stop the program then the lag is gone. Strangely I did try turning that off (and even uninstalling it) with the previous install. It did not help there.
I can't believe it, but I fixed my severe Windows 10 VM stuttering issue. I was really hopeful that the MSI fix proposed above (I used MSI_util_v3.exe to enable msi, and set the interrupt priority to "High") was going to work for me, since lspci told me that my gpu+audio passthrough didn't have MSI enabled. Applied the fix, no dice.
Then I resumed my two-day Google-fu and read like a thousand and one posts with all sorts of purported arcane fixes. I'm one post removed from sacrificing a virgin and using his blood to consecrate my VM.
It turns out that this was my problem (see attached picture). I enabled this to run WSL, and I didn't suspect that it would cause a major issue with lag and stuttering. This was my last hail-mary, and I disabled it, rebooted the VM thinking it wouldn't do anything.
Granted, I can't use WSL in my VM anymore but it wasn't that important compared to having the VM run smoothly. Now I'm streaming 4K videos on youtube on the VM through Parsec and everything works perfectly.
Sorry for the late reply. It happened before the update as well. Quite soon after my last post, I started running Unraid om my old hardware and just used my VM that had all these problems on the new hardware. There were no problems then. So bare metal works just fine.
A week ago, I got a new GPU. And since my old hardware is not fast enough for my Unraid system anymore, I decided to give it another try today to see if I could get a Windows 10 VM running. It runs much better with a few changes. I switched back to bare metal for now until my new PC case is done. Then I will make the switch back to using a VM on Unraid and put a description of my performance with the new hardware on here.
Hey yo. You could try passing through a ssd to the vm as the only disk. I.e. eliminate vdisk completely. I did some testing on a VM that I was trying to remove the lag when scrolling on Divinity Original Sin 2. I tried pinning, xml changes, changing cache disks, nothing helped. What did help was passing through the entire disk to the VM (as the boot disk). I also did this technique for my bittorrent VM and got much better download speeds. So maybe give that a shot.
While I did not do that today, I did do that in the past. I passed through the entire motherboard NVME controller. Still laggy. My current guess is that my old GPU was the cause of most of the lag. But there is still some lag.
I think that the amount of lag I saw today was acceptable and is something to be expected from a virtual machine. Bare metal is just a bit faster. When I did a Time Spy benchmark on the GPU, I got about 20.000 GPU score on bare metal and 17.000 on the vm. The vm just gives me a lot worse performance. But when I have it all up and running in a few weeks then I will try to optimize it all.
Here I am in 2024, after two days of pain trying to get my VM back working smoothly... version 6.11.5... tried a hundred things, but this was the thing that fixed the performance issues. I am very grateful for this. RIP WSL.
so i have amd radeon r9 290x gpu. when i launch fortnite it warns me about outdated drivers but i played anyway. but i wanted to play with stretch so i downloaded amd adrenaline but it couldnt find any drivers so i had to manually install it. so i installed the drivers and the software worked fine. fortnite stopped giving me a warning to. but when i got ingame it was really laggy. it wasnt laggy before i updated the drivers. what should i do?
i use tiny11 OS
cpu- intel i5 4460
amd radeon r9 290x
16gb ram
The 200 and 300 series graphics cards have been moved to legacy status, the last Adrenalin package for Windows for your card was 22.6.1 which is coming up on 2 years old. The R9 290X card is over 10 years old. On top of that you're using a 3rd party OS with questionable hardware support.
There's absolutely nothing wrong with maintaining a legacy gaming rig. I still have an old Athlon X2 and HD 5670 on Windows XP with an air gap for when I want to play legacy games. But trying to use decade old hardware with an unsupported OS to play modern games is literally a crap shoot. If you had it working at all at one point I would suggest go back to that configuration.
okay would you recommend that i use windows 10 instead?
and where do i find old drivers to download?
im starting to think that it isnt the driver or graphics card that is the problem. i think my cpu is bottlenecking my gpu. since the 290x still can run most modern games pretty well.
I used to have a 290X also and ran that for many years cause there really wasn't a generational upgrade clear up through the RX 580. But 4GB VRAM just isn't enough any more, unless if by modern games you mean esports titles at 1080p.
okay, i cant seem to find the same driver as i had earlier. i think i didnt have an amd driver. ive been watching videos of people saying and showing that the 290x is still really good in 1080p gaming in modern games
i downloaded the latest driver from amd and when i launch cs2 my graphic card ascends in temp. and the graphic card goes into safe mode or something. i run the lowest settings on it. at the moment im trying to find a modded driver that unlocks my gpus potentiall
The R9 290X reference was always a hot running card. It used the antiquated single blower style fan on a 2-slot design cooler. That's why I converted mine to liquid cooling. You could try blowing the dust out of the heatsink and reapplying thermal paste.
