The hardware gets the attention but the software is what you actually play. Choosing the wrong simulator platform means paying for courses you will not enjoy or missing the multiplayer community you wanted. Here is the full comparison.

The Major Platforms: What Each One Does Well

The three platforms that dominate home golf simulation are E6 Connect, GSPro, and TGC 2019. They differ in course library size, physics quality, compatibility, and pricing structure. E6 Connect: the polished option for famous courses. E6 has licensed the actual course data from Augusta, St Andrews, Pebble Beach, and other major venues. If playing a well-rendered version of a specific famous course is your primary goal, E6 has the best licensed offerings. Compatibility is broad: over 80 launch monitors work with E6. The subscription model starts at $199/year for the basic tier, scaling up to $499/year for the premium tier with more courses and features. GSPro: the choice for physics and course variety. GSPro uses a proprietary physics engine that many serious golfers find more realistic than competitors. More importantly, the GSPro community has created and shared over 200,000 courses, including most notable real-world courses and thousands of fictional designs. If you want to play Bethpage Black or Augusta National without a licensed version, someone in the GSPro community has built it. GSPro costs $299 as a one-time license with no annual fee. TGC 2019: the multiplayer and league option. The Golf Club 2019 has the strongest infrastructure for organized competitive play, including handicap systems, league management, and tournament brackets. The community course library exceeds 150,000 courses. Annual subscription is $99/year, the lowest of the three major platforms. Graphics are older but functional.

Compatibility: Matching Software to Your Launch Monitor

Not all software works with all launch monitors. Before purchasing any simulator software, verify that your specific launch monitor model is supported. E6 Connect compatibility: the broadest compatibility of the major platforms. Officially supported launch monitors include Garmin R10, SkyTrak, SkyTrak+, Bushnell Launch Pro, Rapsodo MLM2PRO, Uneekor QED and EYE XO, Foresight GC3 and GCQuad, Trackman, FlightScope, and many others. Check the E6 website for the current full list, as compatibility is updated regularly. GSPro compatibility: narrower than E6 but covers the most popular monitors. Officially supports Garmin R10, SkyTrak and SkyTrak+, Bushnell Launch Pro, Uneekor devices, Foresight GC3 and GCQuad, and a selection of others. The community has developed unofficial bridge software for some additional monitors. TGC 2019 compatibility: supports most major launch monitors through TruGolf integration and third-party bridge software. Coverage is similar to E6 but with some differences at the edges. The compatibility question is especially important for budget launch monitors. A Garmin R10 works with all three platforms. A less common mid-range monitor may work with only one or two. If you already own a launch monitor and are choosing software, start the decision from compatibility, then weigh features and price.

Pricing Over a 5-Year Horizon

The right way to compare simulator software costs is over a multi-year horizon, not at the point of purchase. Year one costs: E6 Connect basic tier $199, GSPro one-time $299, TGC 2019 $99. Five-year total (assuming no price changes): E6 Connect $995, GSPro $299 (no recurring fees after initial purchase), TGC 2019 $495. This makes GSPro significantly cheaper over a five-year period despite the higher upfront cost, assuming you continue using the platform. The calculation changes if you want E6 premium features: $499/year for premium E6 would cost $2,495 over five years. Important caveats: E6 and TGC occasionally offer discount pricing during sales events, particularly in late fall and early winter when demand for indoor golf products peaks. Waiting for a sale can reduce the effective annual cost. GSPro periodically releases updates that have historically been free to existing license holders, though this policy could change. Some launch monitors include free trials or bundled software that delays the need to purchase a subscription. A Bushnell Launch Pro purchase includes certain E6 Connect access. Evaluate these bundles as part of the total hardware-plus-software cost calculation. The correct framing for the decision: if you are price-sensitive and will use the simulator for many years, GSPro one-time cost wins. If you want a specific premium course library or the broadest compatibility, E6 at the basic tier is competitive. If multiplayer league play is the primary use case, TGC at the lowest price point may be the best value.

Hardware Requirements for Simulator Software

All three major platforms require a Windows PC or, in some cases, an iPad or Mac. Check the specific requirements for the platform and version you plan to purchase. Minimum PC specs for smooth play: a dedicated GPU (NVIDIA GTX 1060 or AMD equivalent at minimum; RTX 3060 or better recommended for modern graphics settings), 16 GB RAM, an SSD for faster load times, and a processor from the last five years. Older hardware will run the software but may experience frame rate drops, especially during course flyovers and with higher graphics settings. Resolution and display: simulator software is designed to look good on projector screens and large displays. Running at 1080p is the standard; 4K support exists but is demanding on the GPU. The practical sweet spot for most home setups is 1080p at 60 fps, which most mid-range gaming PCs from the past four years can achieve reliably. Projector input lag matters: simulator software is turn-based, so input lag affects the visual experience of watching your ball flight, not the data capture. A projector with 30-50ms input lag is acceptable; 20ms or less is ideal. Gaming-spec projectors from major brands (Optoma, BenQ, ViewSonic) are generally better on this metric than general-use projectors at the same price point.
