PUBG: Battlegrounds

Why this game, specifically

PUBG streams a large map continuously and loads most of it under time pressure during the drop. That makes storage throughput, memory availability and background disk contention the parts of Windows worth checking, more so than anything in the graphics path. ORION reports what it finds rather than assuming a fixed answer for every drive.

What ORION checks

• Storage housekeeping: temporary data, launcher caches and driver shader caches that grow without bound.
• Memory pressure: page-file configuration, memory compression state and the caching services that compete for RAM.
• Background activity: startup entries, scheduled tasks and always-running apps that take CPU time while a game has it.
• Power behaviour: the active power plan, processor power management, and device idle policy, including whether the machine is on battery.
• Network configuration: DNS, adapter power settings, congestion provider, and the supported TCP options Windows exposes.

Recommended changes

Broadly appropriate, low expected side effects, and reversible where the badge says so. These are catalog entries, not a script: ORION reads the current value on your PC first and skips anything already set.

• Enable Game Modegame-mode SafeFreeReversibleNo restart

  Turns on Windows Game Mode so the OS prioritizes the active game.

• Enable Auto Game Modegamebar-auto-mode SafeFreeReversibleNo restart

  Lets Windows automatically apply Game Mode when a game is detected.

• Disable Game Bar background recordinggamebar-bg-off SafeFreeReversibleNo restart

  Keeps Game Bar background recording off until you turn it back on.

• Disable Xbox Game DVRgame-dvr-off SafeFreeReversibleNo restart

  Stops Xbox Game DVR from recording in the background while you play.

• Reduce gaming notificationsfocus-assist-gaming SafeFreeReversibleNo restart

  Turns off a common notification surface while leaving Windows security notifications alone.

• Maximize DirectX shader cachedx-shader-cache-max SafeFreeReversibleNo restart

  Maximizes the DirectX shader cache to reduce compilation stutters.

• Block Delivery Optimization uploadsnet-do-upload-limit SafeFreeReversibleNo restart

  Stops Windows from uploading cached updates to other PCs.

• Clean Steam web cacheclean-steam-htmlcache SafeProNot reversibleNo restart

  Clears Steam's in-client web cache.

Advanced options

Legitimate changes with real trade-offs: hardware dependence, power draw, or behaviour that varies between systems. ORION shows these separately, records the previous value before writing, and never folds them into a one-click run.

• Disable memory compressionmemory-compression-off ModerateFreeNot reversibleRestart required

  Turns off RAM compression so paged-out memory goes to the pagefile instead.

• NTFS large memory cachentfs-memory-usage-max ModerateFreeNot reversibleRestart required

  Increases the NTFS in-memory cache for heavy file workloads; reversible, needs a restart.

• Superfetch boot files onlymem-superfetch-boot-only ModerateEliteReversibleNo restart

  Limits Superfetch to boot only - reduces background SSD writes.

• Enable TCP window scaling & timestampsnet-1323-window-scaling ModerateEliteReversibleRestart required

  Enables RFC 1323 window scaling and timestamps for higher-throughput links.

Trade-offs and limits

• Shader-cache cleanup frees space but forces the next run to rebuild the cache, so the first session after a clean can stutter more, not less.
• Storage and memory options are the ones that most depend on how much RAM and what kind of drive you have. ORION reads both before it recommends anything.

ORION does not publish a frame-rate figure for PUBG: Battlegrounds, because we do not have reproducible before-and-after data for your hardware. What the app can do is capture frames on your PC, in your game, before and after a change, and show you that.
