• There seems to be an up tick in Political commentary in recent months. Those of us who are long time members of the site we know that Political and Religious content has been banned for years. Nothing has changed. Please leave all political and religiours commentary out of the fourms.

    If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.

    Please note any post refering to a politicion will be considered political even if it is intended to be humor. Our experience is these topics have a way of dividing the forums and causing deep resentment amoung members. It is a poison to the community. We apprciate compliance with the rules.

Over the past few days, I’ve been experimenting with ChatGPT and DeepSeek to push the limits of my P3D v4.5. I’ve been chatting with AI about what I can tweak in the P3D system (mainly the Prepar3D.cfg) to achieve the best graphics and performance. Here's the result: I’ve never seen this level of detail, color, and lighting in my sim before! And all of this with virtually no FPS drop (I gained about 8–10 more FPS) and without heavy VRAM (only 1GB more) usage. I don’t have a dedicated GPU; this is all thanks to the integrated Vega 11 in my processor. Definitely worth a try!

Yes sure this process can work and can be customizable for all sims (the only thing you need is patience and time to check every modification one by one).

First of all, I asked both GPT and DeepSeek to check, correct, and analyze my .cfg files (such as prepar3d.cfg). Then, I told them I wanted to improve the graphics and eliminate the cartoon-style look to make the sim as close to real life as possible. DeepSeek had me modify several settings in the prepar3d.cfg (I tested each change carefully, no more than two at a time, to avoid compromising the sim's stability). Several times, I told both GPT and DeepSeek that I wanted more detail and the best possible graphics without sacrificing performance. Step by step, they guided me in tweaking shaders, ASP3D settings, REX Sky Force, and bring me to finally install ReShade with a custom preset designed to best replicate real life visuals.
The sweet spot ended up being certain values in the [TERRAIN], [SCENERY], and [DISPLAY] sections — especially settings like [JOBSCHEDULER] AffinityMask=85. Since my PC doesn’t have a dedicated GPU, DeepSeek recommended installing Process Lasso to better manage system resources for P3D.

Now the best part is that I don't even remember all the steps I followed because I spent several days optimizing and that's where AI really shines. I ask now GPT and DeepSeek to give me a detailed summary, and here it is (see attachment)!
