Unstable fps + fps drops on eGPU while playing games in bootcamp Windows 10 (ex. COD: warzone)
I’ve been having some problems with low unstable FPS and FPS dips in games, in particular with Call Of Duty: Warzone.
does anyone have these problems when gaming with their eGPU? Or is this to expect from an eGPU over Thunderbolt 3, are these bandwidth limitations? Or is there any settings i should have a look at? Or any other drivers that need updating? Thunderbolt drivers? PCI.ini Fix (as i have taken ownership of the file)? Bad AMD drivers (I have done DDU reinstall of drivers)?
Anyone else have these problems?
I really hope someone can help me with this as I feel Im at the end of my possibilities.
My setup is:
Latest AMD adrenaline 2020 drivers installed (version 20.3.1)
I boot into windows via EFI boot, AMD dGPU disabled, intel iGPU running my macbook pro screen, eGPU running my UltraWide monitor.
I also use Windows 10 bootcamp Only for playing games.
Did you manage to fix problems ?
I'm having the same problem too! I'm using a Razer Balde 14 with at 6700HQ and a Aorus RTX 2070 eGPU. I have installed the increased Host 2 Device Thunderbolt firmware to increase the bandwidth a bit between my computer and the eGPU. I have amazing frame rates in standard Cod MW multiplayer maps and most of the time in Warzone but anytime I'm in a large field or looking over a large portion of the map (ie: looking from the edge towards the center of the map) I always get frame drops from about ~80fps to ~45fps. I'm still unable to figure out what the problem is quite yet but I have a feeling this is a limitation of the speed of Thunderbolt 3. My 2070 has tons of power to push this game at its current settings but gets starved by the CPU not having enough bandwidth to let the GPU to know what to render. I have a feeling this could be fixed by a draw distance setting that may put us at a disadvantage. I know you can get a more steady frame rate by dropping CPU based settings like Anti Aliasing. I'll let you guys know if I can find a solution, but as of this past update (1.18) it still seems to be a problem.
@lawless_heaven, Aorus' eGPUs have USB hubs built in like most other enclosers so they allot a portion of the 40Gbps of Thunderbolt to the USB hub. So installing this different variant of firmware for the Tunderbolt controller removes that allotted portion giving the GPU more headroom but at the cost of the USB hub being much more finicky. I used a designated USB hub already so it's not a huge problem for me.
I think it is related to Warzone game as it is an online game and connecting to a server all the time.
@gamesonmacbookpro, Yeah but the only people that have the exact same FPS drops only in CoD Warzone that I've been able to find out is people with eGPUs. Though the game is poorly optimized, people with their GPUs in a 16x PCIe slot can't seem to recreate the problems I'm having leading me to believe it's to do with the Thunderbolt 3 connection.
