2019 13" Dell Inspiron 13 7391 2-in-1 [10th,4C,U] + GTX 1080 @ 32Gbps-TB3 (AORUS Gaming Box) + Win10 1909
- DELL Inspiron 13 2-in-1 7391, i7-10510U, Intel UHD Graphics, 16GB LPDDR3, PM991 NVMe Samsung 512GB SSD, Windows 10 1909 Home (USA version contains 32GB Intel Optane boost for the SSD)
- 40" Philips BDM4065UC (60hz, 40", 3840x2160 at 8bit per channel)
- RenkForce active USB3.0 Hub
- Corsair K70 Lux keyboard
- Havit vertical mouse
- LogiLink 7.1 USB sound card
- Pluggable Gigabit LAN USB-adapter
(note to the picture above: I did dim the laptop screen on purpose; it can be quite bright)
(note to the picture above: from top to bottom: active USB3.0 hub, USB sound card, volume control)
(note to the picture above: yes - I have 2 USB-C-like cables, one TB3-cable for the eGPU, one from the DisplayPort of my screen to the USB-C-/TB3-port of my laptop)
(note to the picture above: HWInfo64 information on the TB3 port)
- Performed all BIOS- and driver-updates through DELL Update
- Installed Intel Driver & Support Assistant
- Uninstalled DELL Intel UHD Graphics driver
- Updated all drivers using Intel Driver & Support Assistant,
installing the Intel UHD Graphics driver in place of the (older) DELL one
- Installed all USB-devices into the active USB3.0 hub (not the Aorus Gaming Box - it feels to me like it made some difference)
- Optional (may help with stuttering issues): deactivate C3-states and/or Intel SpeedStep in BIOS (reduces power safety features) - this turned out to not be necessary after the latest driver updates and using the active USB3.0 hub
- Optional (may help with stuttering issues): DELL USB-C Patch.
I have not tried using any other OS on this laptop, but I will enhance this section if I do.
- As you can see you are better off gaming in 1920x1080 via external display
- High Quality -> Ultra Quality (both in 1920x1080 with 8xAA) = -4fps on average
- Disabling AA on High Quality settings in 1920x1080 (internal display) makes the average FPS jump to ~100fps
- Internal iGPU runs 1920x1080 on low settings (internal display) at about 20-30fps
- 3840x2160 on High Quality (external display) w/o AA can be playable - depending on the game
Since I am only really playing RocketLeague, I cannot really test with anything else unless you offer me a Steam Key (if there is one; I do not want to install UPlay, Origin or Epic).
Pros / recommendation:
- Use the Gaming Box (GTX1080) for games only
- Less noise
- Less stuttering (though mine almost went away with latest driver- and BIOS-updates)
- Prefer 1920x1080@High/Ultra Quality with some AA
- 3840x2160@High Quality w/o AA may also work
- Use iGPU for office / browsing
- Usually sufficient performance for regular applications (e.g. development, Word, etc)
- Much quieter
- Can drive a display via HDMI or USB-C (I am using DisplayPort-to-USB-C-cable and it works with my monitor)
- Really bad for games
- Use active USB3.0 hub for your devices (usually seems to work better)
- Refer to this thread where I noted a few solutions to the problems I had a bit more in-depth and feel free to ask questions
Nowadays I use this set up as my main driver for everything: graphics design, development, audio- and video-editing and gaming and I am loving it, because it is always mobile!
A Desktop is much quieter while performing somewhat better.
just a small feedback (possibly with a big impact).
Today I got myself a MSI Prestige PS341WU WUHD-monitor (5120x2160) and it seems to have changed everything. The drawback is, that on iGPU I have 5120x2160@50hz, though since I do not play games, I absolutely do not care about it. Using the Aorus Gaming Box 1080, I am using DisplayPort and I get 5120x2160@60hz.
Even though not as obvious, I still used to have that weird "screen-lagging" in the past using the Philips BDM4065UC monitor. It happened on the eGPU more often and obvious than on the iGPU (Intel), but it did "lag"/"freeze" for milliseconds on both.
Using the new monitor (MSI Prestige PS341WU) I do not have any problems with 4k or 5k2k resolutions anymore at all. No Lagging whatsoever - all the problems from the post above are gone.
Therefore the key-takeaway for me is, that if you do experience trouble at 4k or above - at least on this laptop - perhaps your monitor might be the issue and hence try using a different monitor.
