Release Notes for Update 3 for RTX64 3.7

This update adds support for Windows 10 Feature Update Version 2004 and resolves various issues as detailed below. This is a cumulative update that contains all of the fixes included in Update 1 and Update 2 for RTX64 3.7.

New Features

• Adds support for Windows 10 Feature Update Version 2004 (Windows 10 June 2020 Update). (9474, 9501)

NOTE: Due to changes in Windows 10 Feature Update Version 2004 and how RTSS is able to communicate with Windows, RTSS-to-Windows interaction is several times slower than with other supported Windows 10 updates. As a result, you may notice slower interactions between RTSS and Windows, such as during inter process communication (IPC) between an RTSS process and Windows process, or when using the RTX64 Virtual Network. Slower Virtual Network performance is more likely to occur on systems where only one processor is assigned to Windows.

IMPORTANT! You must install the latest HASP driver before you can use Update 3 for RTX64 3.7 with Windows 10 Update Version 2004.

Issues Resolved

• Resolves EEPROM checksum errors with the RtI10GB driver.
• Resolves an issue where incorrect values were read from the PCI config space for the CheckForNetworkCard routine in the RtI10GB and RtIPCH drivers. (9497, 9447, 9448)
• Resolves an issue with the RtI10GB driver which contained an invalid check for receive events in the Interrupt Service Thread (IST). (9502)
• Improves interrupt latencies caused by too many concurrent SMIs (System Management Interrupts) generated by the UEFI BIOS and other software. (9495)
• Provides an updated Rtx_rtss.lib object file library, available in the Update_3_for_RTX64_3.7_SOURCE_XXXXXXXX.zip on the Support site, which resolves build errors that resulted when building applications containing C++ STL (Standard Template Library) classes in Visual Studio 2019 version 16.6. (9487)

Known Issues

• RTDLL projects created by the RTX64 RTDLL template do not build when the configuration is set to RTSSRelease. This issue is fixed in RTX64 4.0.
• Uninstalling the RTX64 SDK from a machine running Update 3 for RTX64 3.7 on Windows 10 Update Version 2004 might cause the HASP driver to become corrupted. One symptom of HASP driver corruption is a lag in Control Panel responsiveness. If HASP corruption occurs, reinstall Update 3 for RTX64 3.7. (9587, 9582)
