Please tell me how to get gold on a the upper tier license trials lol
To get tailored advice from people much better than me here, best thing you could do is upload a video with the ghost car where you got your absolute best time.

But in general I use a binary chop method of setting my time distance to the ghost car at the same level I am missing the Gold by until I improve by half that time distance.,

Then I watch to see where the ghost pulls away from me on the next run, and then go back and review that part of the demonstration, paying attention to road position, entry and exit speed, gear choice, brake timing, braking duration and the amount of steering turn being applied and when - which surprisingly scrubs a shed tonne of speed compared to not steering and driving in a straight line.

If all that fails, I then reduce traction control level to zero while racing on straights as it allows for higher top speed - picking it in the hud with d-pad left/right while racing, and dynamic adjustment using d-pad up/down - and keep it as low as possible anyway, much like I drive with minimal features for steering correction, lighter abs, etc.

Here are my findings from the different modes when locked to 60hz. And I've revisited it numerous times over several hours.
  • Resolution mode with PSSR enabled gives me lower fidelity, but RT interiors and reflections.
  • Resolution mode with PSSR disabled gives me higher fidelity but no RT reflections.
  • Prioritise Frame Rate with PSSR, gives me high fidelity and excellent RT reflections.
  • Prioritise Frame Rate with PSSR disabled, gives me high fidelity but lower quality RT reflections.
The easiest way for me to tell is the speed of the reflections and the quality of them on shiny car paint work. I did all my testing in cockpit mode and in a car which has a shiny gloss hood and external paintwork going/extending into the interior. I also ignored replays to ensure my findings were realtime whilst actually driving. I used two testing circuits, Tokyo Express at night and Weather Tech Raceway in morning.

Hope that helps.

Just tested this. It appears that the RT in Prioritize Framerate does not include car-on-car reflections. Used a car that has a silvery back. On Prioritize RT, could clearly see other cars coming. In Framerate, could not.

But, overall, Framerate + PSSR still preferred option.

PSSR (1440p?/69fps : 14.49ms per 1f) vs. TAA (1800p/76fps : 13.15ms per 1f)
Can someone please correctly calculate the cost of PSSR? 1.34ms? 2ms? 3ms?

Unless you want interior RT. Then by far the best mode for me is Prioritise Frame Rate and PSSR on locked to 60hz. Excellent image fidelity whilst giving superb RT reflections.

Whatever mode you settle on, this is a superb update.

You dont get RT in performance mode mate. Its cube maps.

The game has a rare bug where RT will fail and it resorts to cube maps. Happened to me a few days ago and it looks exactly like performance mode.

The reflections change when its in performance mode. The way they bend over the car. Its obvious when u change back and forth.

You want RT. Put it in RT/Resolution mode.

You are wrong King, watch the video. The only way to get RT is with the Resoultion/RT mode. You only get cubemaps on the Frame Rate mode.
You say the "Resolution mode with PSSR disabled gives me higher fidelity but no RT reflections." that makes no sense for the Resolution mode to not give RT. If you play outside cockpit this is the best mode.

•RT/resolution - PSSR - Full RT, upscaled Res.
•RT/resolution - 4k - RT only on exterior reflections.
•Performance mode - PSSR - No RT, upscaled res but higher then RT mode, higher lod.
•Performance mode - 4K, No RT, higher lod.

8:10 in the video. Dont understand why he's using replay to test frame rate. Replay cranks up the visuals from what i understand. Its not indicative of what the actual gameplay performance is like.

Doing that same track with 20 cars, wet weather behind all of them doesn't budge the frame rate running it in 4k, RT/Res.

I think it was just as an academic benchmark to test the limits of the engine/PSSR cost.

Yeah, was thinking that afterwards. I have to rewatch it a bit slower because i feel some details have been missed. DF seem very vague these days. No mention of higher lod in performance mode. Higher close up poly count in RT mode.
Anyway, respect his work as always.

I love that cube maps as a solution are still so effective that people often can't tell the difference between that and RT.

Same with The Crew Motorsport. A lot of people think it got RT reflections in the pro patch because cars can reflect off-screen elements like the sky, cloud formations etc....but they are just using cube maps which replicate RT really effectively.
 
A little off topic, but since this is the hot GT7 thread right now, is there any way to unlock everything without actually playing the game's campaign? I don't have the time to sit down and progress through the game, I just want to drive whatever car and track I want.
The game doesn't have a traditional campaign. It has menu books.

Unfortunately everything is tied to the menubooks, tracks, events, features, etc. You don't have access to majority of the tracks until you complete menu books. It shouldn't take too long and honestly does a great job at introducing the game.

Replays with gameplay cameras are the same visual settings and framerate as in gameplay. In the ps5 version, replays with the chase cam gameplay camera didn't have RT reflections like the cinematic replay camera angles do. The replay feature in gameplay cameras lets him compare the exact same scene between differences in performance and RT on or off. He can boot up that replay save on the PS5 version and compare the exact same gameplay there too.

No, you're right.

After trying each mode I think Frame Rate/Performance Mode, 120fps, PSSR 'On' has the best combination of looks and performance.
I only did the RT mode which to me didn't look much different from the base PS5 version aside from cockpit mode having slightly better reflections on the speedometers?
