Canon R5 sharpness with 100-400 ii and buffer issues

Hello everyone!
First of all, english is not my first language and I apologize for any mistake.
I've been doing bird photography for the last 10-12 years but I'm getting somewhat desperate with my new R5 these days... I got some serious buffer issues and the image sharpness is really bad compared to my old 5Dmkiii.
First, the buffer issue : whenever I do burst shots, my buffer starts around 40-45 pics available and after the first 3-4 shots it drops down to 20 before I can take maybe 10-12 shots if I'm lucky. This could be tolerable, but the buffer takes up to 90 seconds (timed it) to get transferred to the CFExpress card (Sandisk) and even when I'm up to around 13-15 shots I can only take one shot before it goes down to 0 again! I've tried this with multiple CFExpress cards, SD cards (300mbps) and the result is always the same. I shoot raw and save on a single card. The only time the problem seems to be somewhat less present is when I shoot without a lens and with the cap on and it seems to be worse when I continuously need to focus on my subjects. Needless to say, I missed a lot of shots this way.
As if this wasn't enough, picture quality with my 100-400 ii, which was super sharp on my 5Dmkiii, is really bad or at least hit or miss with mostly misses. I'll include pictures below to illustrate what I mean (100% crop). I'm also using the Canon TC1.4x iii, but was also using it before without any problem on my old camera, getting super sharp shots.
Yesterday I saw a Boreal owl (quite rare where I live), and it flew towards me before landing no more than 10 feet from me (was not baiting). With my 5Dmkiii I would have nailed that shot super sharp since it was really an easy shot. When I looked at my pictures I was really frustrated with the results since they were really not sharp at all. I tried using servo AF and one-shot AF, animal eye dectection AF, spot AF and got mostly the same results (RAW, IBIS on, ISO AUTO (2000), f/8, 1/800s to 1/1600s). Attached below is one of many "missed" shots and one of the few where the feathers are a bit sharper (less than 5% of the files). I also added a picture of a duck in a different setting, but again with the same softness problem. I was wondering if the use of the 1.6x-cropped frame mode sometimes could be the culprit, but even when using full frame I get this problem.
Stores are closed right now where I live, but I'll send the body to Canon to fix the buffer issue when they open back. However, I'm curious to see if anyone else had these problems. I'm also worried that even if they fix the buffer issues, I'll still end up taking pictures that are not sharp.

Message about the obvious - R5 with 1.4x and 100-400
Did a quick image this evening of the moon in a hazy sky. Since I am still thinking about options for long lenses, I used my EF 100-400 MKii with a 1.4x Mk iii and an off brand EF-RF adapter. The photo is nothing special, but it was hand held and I am impressed with the abilities of this camera, its focus, and the IS. But, when I shut the camera down a message appeared: "Keep the lens cap on after you turn the camera off." Maybe that message is always there and I never noticed it before since I usually turn the LCD around to protect it. I just thought it was kind of humorous.
Anyway, I will not give up this lens for the RF 100-500 after seeing this result (1/800; f/8; 490 mm; ISO 640 hand held. No processing except for some cropping)

Backfocus with any 70-200 ( RF, EF 2/3) and canon R5 in Servo
- By Dmitri_Kahm

Hi everyone! I am a photographer for Russia, Moscow.
As many people here I initially had a lockup/freezing issue with my R5. I recently sent it to CPS-Russia (main office) and they replaced the circuit board under warranty and also updated the firmware. That helped.
BUT! After receiving my body back I encountered that now when using a servo-mode (any type) and a 70-200 ( I have RF 70-200, but also tested another RF, and EF 2/3 USM lenses) I have severe backfocus especially at a tele-end (200 mm) and for distant targets that are approaching me ( skiers, snowboarders, cars etc.).
Originally I found it out during skiing competition ( I am a sports shooter).
Then I ran several tests with different lenses shooting approaching cars and had the same bad results. There is clear backfocus( several meters!), whereas DPP in 99% of the time shows the focus point where it was intended to be.
The test were run outside during daylight and a temperature of around -10 Celsius with:
- latest firmware for both all lenses and body;
- R5 + two RF 70-200/ EF 70-200 USM 2, EF 70-200 USM 3 ( all lenses were tested for optical quality by CPS, an they all were provided by CPS for test except for the RF lens I originally own);
- Several different Sandisk Extreme Pro SD-cards,
- Several different original batteries;
- various FPS;
- servo spot af/1-point af/intelligent tracking with initial point af choice;
- at 200 mm 90% of time, sometimes around 150-175mm;
- ISO ranging from 100 to 1000;
- shutter-speeds from 1/1250 to 1/3200;
- IS on/off;
- lens focus distance limiter on/off;
- mechanical shutter/electronic 1st curtain;
- cars approaching me at the speed about 30-60 km/p/h;
around 50+ meters distance to cars ( at closer distances the backfocus is less severe)
- I even invited an engineer from CPS as well as independent photographer to run the tests with me and to shoot themselves.
Result: same backfocus in most of the cases whatever we did.
I attach an album with one of the series and a DPP printscreen. If needed I can upload more.
The yellow taxi in the photos is supposed to be in focus. However it is blurred whereas the truck behind it is much sharper! Look at the plates. DPP shows red square on taxi for the whole series. It is only one of the series but I have many. If you really want I can upload them but hope you will believe me.
After that we tested ANOTHER R5, that is owned by CPS and is given for tests/as a replacement - SAME RESULT!
Unlike mine CPS R5 is said not to have ANY service history except for the firmware updates.
When checked according to CPS procedures NO PROBLEMS are found with any of the bodies.
So, though the engineers clearly see that something is wrong they can do nothing concerning the repair or replacement. I was told that Servo AF can not be checked by their equipment and is considered to work fine out of the box as long as the 1-shot af works fine ( it does).
We are all at a complete loss. We filed a ticket to Canon Japan but the guys from CPS do not expect to receive a quick answer or any real resolution.
Actually it might be that CPS somehow messed up both cameras not knowing that, but they will never admit that...
I really need your help in further tests! I would appreciate if the owners of R5 and 70-200 tested their cams in similar conditions and reported the results.
( 200 mm of 70-200, servo, approaching cars, distance 50+ meters, actually the further you start shooting the car as it is approaching - the better).
Is there anyone with similar problems or maybe heard of someone?

The Secret of the Broken Element: A Canon RF 100-500mm f4.7-7.1 Teardown
In ancient times, the IS unit in Canon EF lenses was physically locked down, so the unit didn't make rattling noises when the lens wasn't powered up. Canon decided the lockdown was no longer necessary in modern times, so some RF lenses, like the Canon RF 100-500mm f/4.5-7.1, rattled when the...
