Edits Discord's settings.json to turn off GPU hardware acceleration (frees a chunk of GPU/VRAM while gaming). BEST-EFFORT: it edits a per-user config file, so it may not apply if Discord is open or stores settings elsewhere. Revert re-enables it. Close Discord before applying.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
