"gDEBugger is a fantastic Debugging and Profiling tool. Using the built-in graphing tools, I was able to quickly track down where the bottlenecks were in my application. Having the OpenGL command stream right there great - I was able to improve performance by 40% just by removing all the redundant calls. I recommend it for anyone doing real-time graphics using OpenGL."

Jiawen Chen,
Graduate Student, MIT

"Our process of implementaing general purpose computer vision algorithm on the GPU has become significantly more productive since using gDebugger. I found a major error in our complex multipass rendering implementation within minutes. And best of all - I didn't have to add hundreds of lines of debugging code! Profiling is simple with the seamless integration of counters provided by Nvidia perfkit instrumented driver. Got a 21% speedup."

Jan Woetzel,
Research Assistant, University of Kiel

"Although we are just beginning to use gDEBugger, it has already proven to be a powerful tool in profiling graphics performance. It has an intuitive user interface and it is robust enough to handle our gigantic application and can profile long simulations. It is so easy to capture and compare statistics with gDEBugger. I am extremely happy with this product."

"gDEBugger is a great safety net for all OpenGL programmers!"

Harold Hunt,
Director of Engineering, StarNet Communications Corp

"I find gDEBugger an invaluable time saver, especially with respect to the ease with which shader states can be investigated. I am currently trying to integrate my code with (very) obfuscated source, and regularly find myself turning to gDEBugger to help me out of dark moments of confusion."

Mike Hudson,
GPGPU Programer

"gDEBugger is a one of a kind. A powerhouse for debugging and profiling, encompassing all the features one would could want during the development of OpenGL applications. It's intuitive interface makes it easy for anyone to pick it up and use it right out of the box without the need to consult a hefty manual. People migrating to OpenGL from Direct3D looking for a PIX equivalent, look no further."

Steven Tovey,
Student, Liverpool John Moores University

"I would like to congratulate you about gDEBugger. It's really a great program that saves days and days of painfull GL debugging and extremely ease of use. gDEBugger helped us a lot to find abnormal GL settings against native OSG (Open Scene Graph) error report. We found gDEBugger to be simple, efficient and meets our needs. I could only recommand, it just helps!"

Igor Kravtchenko,
Senior 3D Programmer, Web site

"gDEBugger is an amazing development assistant tool for OpenGL programming. It illustrates all the running status of your OpenGL program and helps you visually catch the bug in your code with so convenient and friendly UI. Before when developing some rendering algorithms, a small error always costs me long time to print out all the OpenGL status values for debugging and it's really awesome. Currently with gDEBugger, my development efficiency is greatly improved. What's more, Graphic Remedy's academic program support graphics researcher 1 year free license and I appreciate it so much. If you are a graphics researcher using OpenGL development, I recommend you to try such excellent software and it will definitely do you a great favor."

Zhao Dong,

"After I presented it to my class, gDEBbugger became the reference tool for OpenGL training and debugging of 3D applications. From the beginning, the students learned how to optimize their code and use the API in an efficient way!! The best tool in the market!!"

Ing. Didier Desmangles,
Ecole Superieure d'Infotronique d'Haiti

"The first time I heard of gDEBugger was in the tutorial "Using the Graphics Processing Unit for Computer Vision" by E. Scott Larsen in CVPR 2006 where he suggested gDEBugger as the best debugger for GPU programming. I think that gDEBugger has far exceeded my expectation for handling the issues of debugging openGL programs. I think gDEBugger is a must have for anyone intending to use OpenGL and would be especially helpful when performing scientific computations using the GPU."

Mani Thomas,
Student, University of Delaware

"gDEBugger is one of the most valuable tools for OpenGL software development. The need to litter the code with glGet* to gain a minimal insight used to be a major setback. Debugging OpenGL is still a challenging task, but it becomes manageable with gDEBugger. It changed the debugging process from disaster management to preventive analysis of suspicious code fragments. The state comparison tool is particularly helpful since it allows finding accidental state changes in no time."

Malte Clasen,
Research Assistant, Zuse Institute Berlin

"gDEBugger is the most important tool for everybody out there, who wants to create error free OpenGL applications. The hardware counter support, as well as the ability to correct shader during execution are features which nobody should miss."

"With the advent of next-generation multi-platform game middleware, gDEBugger is becoming a must-have tool to help game developers achieve both performance and portability."


"gDEBugger has given us an easy and quick way of debugging the rendering pipeline. Within 20 minutes of using the product I was able to identify 3 rendering bottlenecks, and one OpenGL error. In the past, two of these errors would have gone unnoticed (Probably indefinitely). Another nice feature is the texture logging. When using multi pass rendering to render to a texture, it becomes easy to see the exact rendered output of that pass. gDEBugger is a great tool, and I’ll recommend it to anyone Using OpenGL. It’s a Must Have."

Maarten "McClaw" Kronberger,
