CPU	4 cores	6+ cores
GPU	Integrated (with Low GPU)	4+ GB VRAM dedicated

RAM Usage Per Instance

Each Roblox instance uses approximately 300-500 MB. Low GPU Mode reduces this to 200-350 MB.

Alts	Low GPU Mode	Normal Mode
5	~1.5 GB	~2.5 GB
10	~3 GB	~5 GB
20	~6 GB	~10 GB
30	~9 GB	~15 GB

Tip: Enable the Auto-Kill High RAM feature (coming in v2.1) to automatically restart instances that exceed a memory threshold.

Supported Bootstrappers

Alt Central works with any of these. Multi-instance is auto-enabled on startup:

Bootstrapper	Multi-Instance	Auto-Config
Vanilla Roblox	Via mutex holder	✅ Built-in
Fishstrap	Native setting	✅ Auto-enabled
Bloxstrap	Native setting	✅ Auto-enabled
Voidstrap	Native setting	✅ Auto-enabled

VPS / Dedicated Server

Alt Central works on Windows VPS. If Roblox is installed in a non-standard location, create a junction link:

mklink /J "%LOCALAPPDATA%\Roblox\Versions" "C:\Program Files (x86)\Roblox\Versions"

VPS instances typically share GPUs. Enable Low GPU Mode and keep instance count under your RAM limit.
