To participate in the NVIDIA Reflex public test, you must have an Overwatch game license for Windows attached to your Battle.net account, that’s in good standing (i.e. it hasn't been suspended or banned). Additionally, you must have installed Overwatch and logged into the game at least once. If the PTR is not available for you in the Battle.net client after following the steps below, try logging into Overwatch, exiting the game client, and then launching the PTR again.
Step 1: Restart the Battle.net desktop app.
Step 2: Navigate to the Overwatch tab on the left-hand menu.
Step 3: Select "Public Test Region(PTR)" from the “GAME VERSION” drop-down menu.
Step 4: Click "Install" to begin the installation process.
Step 5: Once the PTR client is installed and updated, click "Play" to begin
Once you have the Overwatch PTR client installed, and have the March 11th update downloaded, open the game, go to Options, Video settings, and enable NVIDIA Reflex. With NVIDIA Reflex activated, gameplay will instantly be more responsive, increasing your chances of victory online.
Overwatch also features the Latency Flash Indicator. If you are sporting a new Reflex Latency Analyzer compatible monitor and have GeForce Experience installed, simply enabling the flash indicator and positioning your monitoring rectangle over the indicator location will give you accurate results every time - regardless of hero, ability, or weapon you use.
If you wish to reduce system latency further still, there are a number of system tweaks, game tweaks and hardware upgrades that you can make, detailed in full in our System Latency Optimization Guide.
