I've also latest version of Win 10 (1809 October update). I try to run SR3 with gameloader allrh viles via TP 1.69, the issue "out of memory for tex" happens too.
My GPU is ASUS RTX 2080, what's your GPU?
I patched the 1080p shadow car fix Jennifer file with an hex-editor to modify the resolution from 1920x1080 to 3840x2160. Ok now I create a shadowfix patch @ 1366x768
EDIT: Here's shadow car fix patch @ 1366x768 resolution
For who interested to running Outrun 2 SP @ 4K resolution (3840x2160) with fixed car shadow I've patched the executable from 1080p shadow fix to size internal res to 2160p, shadow patch now working also at full 4K resolution
Good news!! I fixed the error with open an elevated Command Prompt, copy and paste the command below:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V-All
Reboot PC and now Teknoparrot working again!
