available to you under this license (in each case, the "SDK").
This license can be accepted only by an adult of legal age of majority in the country in which the SDK is used. If you are 
under the legal age of majority, you must ask your parent or legal guardian to consent to this license. If you are entering 
this license on behalf of a company or other legal entity, you represent that you have legal authority and "you" will mean 
the entity you represent. 
By using the SDK, you affirm that you have reached the legal age of majority, you accept the terms of this license, and you 
take legal and financial responsibility for the actions of your permitted users. 

You agree to use the SDK only for purposes that are permitted by (a) this license, and (b) any applicable law, regulation or 
generally accepted practices or guidelines in the relevant jurisdictions.

1. LICENSE. Subject to the terms of this license and the terms in the supplement attached, NVIDIA hereby grants you a non-
exclusive, non-transferable license, without the right to sublicense (except as expressly provided in this license) to: 
a. Install and use the SDK,
b. Modify and create derivative works of sample source code delivered in the SDK, and
c. Distribute any software and materials within the SDK, other than developer tools provided for your internal use, as 
incorporated in object code format into a software application subject to the distribution requirements indicated in this 
license.

2. DISTRIBUTION REQUIREMENTS. These are the distribution requirements for you to exercise the grants above:
a.	An application must have material additional functionality, beyond the included portions of the SDK. 
b.	The following notice shall be included in modifications and derivative works of source code distributed: "This software

NVIDIA RTX SUPPLEMENT TO SOFTWARE LICENSE AGREEMENT FOR NVIDIA SOFTWARE DEVELOPMENT KITS

The terms in this supplement govern your use of the NVIDIA RTX SDKs, including the DLSS SDK, NGX SDK, RTXGI SDK, RTXDI 
SDK and/or NRD SDK, if and when made available to you (in each case, the "SDK") under the terms of your license 
agreement ("Agreement") as modified by this supplement. Capitalized terms used but not defined below have the meaning 
assigned to them in the Agreement.

This supplement is an exhibit to the Agreement and is incorporated as an integral part of the Agreement. In the event of 
conflict between the terms in this supplement and the terms in the Agreement, the terms in this supplement govern.  

1. Interoperability. Your applications that incorporate, or are based on, the SDK must be fully interoperable with compatible 
GPU hardware products designed by NVIDIA or its affiliates. Further, the DLSS SDK and NGX SDK are licensed for you to 
develop applications only for their use in systems with NVIDIA GPUs.

2.	Limitations for the DLSS SDK and NGX SDK. Your applications that incorporate, or are based on, the DLSS SDK or NGX SDK 
may be deployed in a cloud service that runs on systems that consume NVIDIA vGPU software, and any other cloud service 
use of such SDKs or their functionality is outside of the scope of the Agreement. For the purpose of this section, cloud 
services include application service providers or service bureaus, operators of hosted/virtual system environments, or 
hosting, time sharing or providing any other type of service to others. 

3. Notification for the DLSS SDK and NGX SDK. You are required to notify NVIDIA prior to commercial release of an 
application (including a plug-in to a commercial application) that incorporates, or is based on, the DLSS SDK or NGX SDK. 
Please send notifications to: https://developer.nvidia.com/sw-notification and provide the following information in the 
email: company name, publisher and developer name, NVIDIA SDK used, application name, platform (i.e. PC, Linux), 
scheduled ship date, and weblink to product/video. 

4. Audio and Video Encoders and Decoders. You acknowledge and agree that it is your sole responsibility to obtain any 
additional third-party licenses required to make, have made, use, have used, sell, import, and offer for sale your products or 
services that include or incorporate any third-party software and content relating to audio and/or video encoders and 
decoders from, including but not limited to, Microsoft, Thomson, Fraunhofer IIS, Sisvel S.p.A., MPEG-LA, and Coding 
Technologies. NVIDIA does not grant to you under this Agreement any necessary patent or other rights with respect to any 
audio and/or video encoders and decoders. 

5. DLSS SDK Terms. By installing or using the DLSS SDK you agree that NVIDIA can make over-the-air updates of DLSS in 
systems that have DLSS installed, including (without limitation) for quality, stability or performance improvements or to 
support new hardware. If you publicly release a DLSS integration in an end user game or application that presents material 
stability, performance, image quality, or other technical issues impacting the user experience, you will work to quickly 
address the integration issues. In the case issues are not addressed, NVIDIA reserves the right, as a last resort, to 
temporarily disable the DLSS integration until the issues can be fixed.
6. Marketing.
6.1 Marketing Activities. Your license to the SDK(s) under the Agreement is subject to your compliance with the following 
marketing terms:
(a)  Identification by You in the DLSS SDK or NGX SDK.  During the term of the Agreement, NVIDIA agrees that you may 
identify NVIDIA on your websites, printed collateral, trade-show displays and other retail packaging materials, as the 
supplier of the DLSS SDK or NGX SDK for the applications that were developed with use of such SDKs, provided that all such 
references to NVIDIA will be subject to NVIDIA's prior review and written approval, which will not be unreasonably withheld 
or delayed. 

(b)  NVIDIA Trademark Placement in Applications with the DLSS SDK or NGX SDK.  For applications that incorporate the DLSS 
SDK or NGX SDK or portions thereof, you must attribute the use of the applicable SDK and include the NVIDIA Marks on 
splash screens, in the about box of the application (if present), and in credits for game applications.

(c) NVIDIA Trademark Placement in Applications with a licensed SDK, other than the DLSS SDK or NGX SDK. For applications

where a credit screen is not present prominently in end user documentation for the application.
(d) Identification by NVIDIA in the DLSS SDK or NGX SDK.  You agree that NVIDIA may identify you on NVIDIA's websites, 
printed collateral, trade-show displays, and other retail packaging materials as an individual or entity that produces 
products and services which incorporate  the DLSS SDK or NGX SDK as applicable. To the extent that you provide NVIDIA 
with input or usage requests with regard to the use of your logo or materials, NVIDIA will use commercially reasonable 
efforts to comply with such requests.  For the avoidance of doubt, NVIDIA's rights pursuant to this section shall survive any 
expiration or termination of the Agreement with respect to existing applications which incorporate the DLSS SDK or NGX 
SDK.

(e) Applications Marketing Material in the DLSS SDK or NGX SDK. You may provide NVIDIA with screenshots, imagery, and
